INTRODUCTION 2.1 CEMQUAL CEMQual is a PC based program, designed to operate under all practically all Windows operating systems. Operation is performed by using simple mouse instructions. CEMQual forms part of an Envirosoft Ltd suite of environmental programs. Envirosoft Ltd environmental programs are: Figure 1 Envirosoft Ltd - Enviromental Programs CEMForm Typical data analysis (normalization and averaging) to provide real time and historical data analysis. Also acts as the interface to other data export programs to provide outputs from processed data. CEMPort Specialist program to summerise emissions data into a format for submission to the authorities or for internal housekeeping or analysis. CEMQual Specialist program to analyse and report drift and validity of analyser calibration, based entirely upon the European standard EN14181. MCERTS Certified. WID Report Specialist Waste Incineration Directive reporting program that provides the data in a dedicated format suitable for submission to the authortites LCPD Specialist power Generation reporting program that provides the data in a dedicated format suitable for submission to the authorities. Covers reports required under the Large Combustion Plant Directive. CEMQual User Manaual v1.13 14/12/11 Page 6 of 71 DOC ID UM13 2.2 THE CEMQUAL PROGRAM CEMQual, a module of CEMSuite, is a specialist program that enables operators to make all the calculations, graphs and reports required to comply with the requirements of the European Standard EN 14181 – QAL3. 2.2.1 EN 14181 EN14181 is a European standard that was written to formalise the methods for assessing the quality of the measurements of stationary source emissions. There are three major parts of this standard: ? QAL1; Quality during manufacture. ? QAL2; Quality after initial installation. ? QAL3; Routine, ongoing quality of the measurements. ? QAL1 and QAL2 are usually outside of the plant operators’ scope, and Envirosoft have only concentrated on the QAL3 part of the standard – the ongoing assessment of the quality of these measurements. This is the most onerous part of the standard to assess as it is ongoing and requires the entry of data from the installed CEMS so that errors in drift and precision may be assessed. An extract from this standard is below: “QAL 3 is a procedure to check drift and precision to demonstrate that the AMS is in control during its operation so that it continues to function within the required specifications for un-certainty. This is achieved by conducting periodic zero and span checks of the AMS - based on those used in the procedure for zero and span repeatability tests according to EN ISO 14956 - and then evaluating the results obtained using control charts. Zero and span adjust-ments or maintenance of the AMS, may be necessary depending on the results of this evalua-tion.” QAL3 requires that both the drift and precision of measurements are checked using control charts. There are many interpretations of how the drift should be checked – CUSUM, EWMA, SHEWHART etc, but only one example of testing for precision, and this is another CUSUM type check. The mathematics behind these checks are detailed within this manual. CEMQual User Manaual v1.13 14/12/11 Page 7 of 71 DOC ID UM13 2.2.2 MATHEMATICAL CALCULATION All the mathematical formulae and calculations used within CEMQual are taken from:- A) BS EN 14181 - Stationary source emissions - Quality assurance of automated measuring systems. B) TGN M20 - Selection, installation, calibration and quality assurance of continuous emission monitoring systems (For the application of BS EN 14181 and BS EN 13284-2) published by the Environment Agency. C) STATIONARY SOURCE EMISSIONS – GUIDANCE ON THE APPLICATION OF EN14181:2004, CEN/TC 264/WG 9N, dated 2008 – 12. 2.3 THE CEMQUAL MANUAL This manual describes the operation and function of the CEMQual program and explains how to use the program to display the information as required. In writing this software and manual, we have used the standard itself, the Environment Agency Technical Guidance Note (TGN) M20, and CEN/TC 264 – Guidance on the application of EN 14181. For information concerning any of the other CEMSuite programs please refer to the relevant documentation. CEMQual User Manaual v1.13 14/12/11 Page 8 of 71 DOC ID UM13 3 SOFTWARE OPERATION 3.1 COMPUTER REQUIREMENTS PC Requirements (minimum) Processor: Pentium 4 or AMD Athlon equivalent Speed: 500 MHz or better Memory: 256 MB (DDR preferred) Display: 1024x768 pixel resolution. 17” monitor or greater. Hard disk: 20 GB Modem: Required for support Operating system: Windows 98/ME/NT/2000/XP/Vista/7 The software will operate on PCs with lesser specifications. However, some operators involve lengthy calculations and the time taken to perform them may become tiresome. 3.2 INSTALLATION The software is provided on CD-Rom. From Windows explorer, or ‘My Computer’, select the relevant drive and run the setup program. Note: If the CD drive has been set for ‘Auto insert notification’, the installation should start automatically. Once started follow the instructions on screen. The installation program creates files and folders and provides a shortcut to start the program from the Windows Start button. Figure 2 CEMSuite Setup CEMQual User Manaual v1.13 14/12/11 Page 9 of 71 DOC ID UM13 Installation continued… NOTE: Once the installation has completed, the PC’s Borland Database Engine will also need to be installed /updated. CEMSuite will start this process automatically. 3.2.1 USB INSTALLATION The software may be supplied with a USB ‘dongle’ and will not function without it being present in a USB socket. To install the dongle drivers, use Windows Explorer to locate a sub-directory on the CD-Rom called ‘Dongle driver’ and open up this sub-directory. Double click on the file called setupdrv.exe and this will install the dongle drivers. The CEMQual program will now operate normally. Figure 3 Borland Database Engine CEMQual User Manaual v1.13 14/12/11 Page 10 of 71 DOC ID UM13 3.3 ASSOCIATED PROGRAMS 3.3.1 CEMSYNC Envirosoft’s program CEMSync should be in operation to copy the historic and live data sets from the DSU(s). This may be seen in the task bar as the following icon: The timing of the CEMSync program operations is: ? Between 5 and 10 seconds past each minute: copy the short term live data set from the DSU(s). ? Between 10 and 25 seconds past each minute: process the above data. ? At 20 past midnight, download the historic data for the previous day and completely refresh the rolling 24 hour data set. 3.3.2 CEMSOCKET Should there be more than one DSU on the CEMSuite system, Envirosoft’s program CEMSocket should be in operation on the task bar; it has the following icon: Figure 4 CEMSync Icon Figure 5 CEMSocket Icon CEMQual User Manaual v1.13 14/12/11 Page 11 of 71 DOC ID UM13 4 PROGRAM OPERATION 4.1 STARTING THE PROGRAM Start the program by double clicking the left hand mouse button on the CEMQual icon; which should now reside on the PC desktop. Alternatively it can also be started by pressing the Windows Start Button > Programs > Envirosoft > CEMQual. 4.2 INITIAL SCREEN After the program has been started a ‘tabbed notebook’ style program provides access to the QAL3 analysis and the configuration pages. On start up QAL3 data for the first measurand will be displayed as either as a spreadsheet style data grid or as a control chart. A quick start guide is now described that should allow the operator to display the QAL3 data immediately.

After it has been configured it is a simple matter to access the QAL3 data, and a step by step list follows: CEMQual will now recall the stored QAL3 and it will appear automatically in the grid area, along with the date/ time, gas bottle ID, and the calculated EN14181 parameters. (If selected, it will appear as a chart). 1. Select the required group by clicking the drop down menu. 2. Once you have selected the group, a list of measurands is generated for that particular group. 3. Now select the time period over which to view the results for, as shown by 3 in the image below; period is expressed in days. Alternatively, enter the start and end dates for analysis manually. 4. To use a manual search, select the ‘start’ and ‘end’ dates then click the radio button ‘As set’ circled by 4A. 5. Data for either the span or zero analysis may be selected by pressing the labelled radio buttons. Figure 8 Quick Start Flow Figure 9 Quick Start Screen CEMQual User Manaual v1.13 14/12/11 Page 13 of 71 DOC ID UM13 5.1 CHARTS After start up, the program will access the current QAL3 data set for the first measurand and display it as a Shewhart chart – discussed later. The data is also available to view in differentways by simple mouse operations, thes are described in this first section. (The factors shown here are used to determine limits for Drift and Precision. More information can be found in CUSUM drift calculation details). These spreadsheets and chart features are now described in more detail. They may be accessed quickly by checking the appropriate box or by individual selection form the top of the chart area. Show or Hide Comments Graph or Spreadsheet Display Scales for the charts. Will default to as set in QAL3 Parameters Chart Appearance Options Select the graph type required for viewing / printing: CUSUM Drift – A CUSUM chart for drift analysis as described in EN 14181. CUSUM Precision – A CUSUM chart for a check on the precision of the measurement – See EN 14181. Shewhart – A Shewhart chart as described in M20. EWMA – An Exponentially Weighted Moving Average chart as described by CEN/TC 264/. Figure 10 Chart Options CEMQual User Manaual v1.13 14/12/11 Page 14 of 71 DOC ID UM13 5.1.1 CUSUM DRIFT With CUSUM Drift selected, clicking on the ‘Graph’ radio button, circled below will bring up a chart similar to the one shown here. Both positive and negative drift are displayed, along with the CUSUM drift limits. Looking at the example above, points have gradually declined past the negative drift limit. Below is how this graph would look in spreadsheet format. Looking at points 13, 14 and 15, they have declined below the drift limit as the text is high-lighted red within the ?Neg column.

There are five parameters that have to be met to show control, and these are detailed in the Environment Agencies Technical Guidance Note TGN-M20, and are when: 1. One or more data points are beyond one of the upper alarm limits; 2. Three consecutive data points are beyond one of the warning limits; 3. Four points among 5 consecutive ones are beyond +/- Sams (Standard deviation for the automated measurement system); 4. Eight consecutive points are on the same side of the mean (NOTE: the CEMQual program only considers samples that are outside of 0.5 x Sams); 5. Six consecutive points are either increasing or decreasing (NOTE: the CEMQual program only considers samples that are outside of 0.5 x Sams.) The warning limits are set at +/- 2 x Sams, and the alarm limits at +/- 3 x Sams. These are drawn on the chart as illustrated above, and are usually coloured in orange and red as seen here. These colours may be changed by the operator if required. Pass / Failure Information Shewhart analysis is demonstrated by either a RED or GREEN bar for each data point. Figure 15 Shewhart Chart CEMQual User Manaual v1.13 14/12/11 Page 17 of 71 DOC ID UM13 Shewhart continued... On the Shewhart chart, each sample is checked for compliance with the 5 conditions above, and then either a PASS or FAIL is indicated by either a GREEN or RED bar, as indicated on the chart on the previous page. Holding the mouse over this bar will indicate the date and time of the check and which of the conditions has been breached. Any point outside the limits automatically requires action, and is highlighted within the spreadsheet grid by both the check measurement and the reference measurement (xt and yt) being coloured RED; if all of these above conditions are met, the numbers are coloured in GREY. This can be seen on the example of the grid below. Figure 16 Shewhart Spreadsheet CEMQual User Manaual v1.13 14/12/11 Page 18 of 71 DOC ID UM13 5.1.4 EWMA Selecting EWMA will produce a chart similar to the one below.

During this operation, the analysis date will be seen to count up and the measurand being analysed displayed just below the ‘Select measurand’ area. On completion, the grid data or chart will update automatically – provided the new data falls within the display dates – this may not be so if the chart has been set to ‘As set’. Should it have been sometime since the data was last analysed, this operation might take a few minutes. The operation may be abandoned by pressing the ‘Abandon’ button – the analysis will be stopped after the current day has been completed. To re-analyse earlier QAL3 analysis, perhaps using different criteria, use the options provided on the ‘Advanced’ tab, see page 59. Click the ‘New data’ button to analyse the CEMSuite data base for new QAL3 Data Figure 23 New Datapoints CEMQual User Manaual v1.13 14/12/11 Page 23 of 71 DOC ID UM13 5.5 PRINTING THE DATA The grids and charts may be printed, either as a print all command or using the current display – either a chart or spreadsheet for the selected measurand, for either ZERO or SPAN. The printer to be used is defined from the advanced tabbed page, please refer to page 61. NOTE: Take care when using the ‘Print all’ feature, depending upon the selection and the quantity of data, many pages may be printed. Spreadsheet data will always be printed in Portrait orirentation, and graphs in Landscape orientation, regardless of the printer set up. If you wish to print just the current graph or spreadsheet for the specific measurand, then click the ‘Print this’ button as indicated in the image below.

Parameter Typical Value Comments N samples 1 May be used to change the factors for the initial QAL3 analysis. In normal operation, this should be set to 1. Skip cals (SPAN) 0 – 6 Normally, calibrations are conducted relatively infrequently (every day). Some measurements however, have very frequent internal calibration routines (hourly) and to plot them all would be undesirable. This value will skip n-1 calibrations before using the analysed data. Skip zero cals 0 – 6 As above, some analysers have regular zero n=but not span calibrations. Span cal.

Clicking the ‘Delete all’ button will delete all measurement configurations, apart from the current one in use. Clicking the ‘Copy to all’ button will copy the current measurement configurations to all other channels. If the measurement configurations are permanent, click the ‘Save’ button for future use. During initial commissioning, these operations may be used to speed up the set up of the QAL3 parameters for all measurands. Once commissioned, however, they should be used with caution to avoid incorrect settings. 6.5 A NOTE ABOUT MEASUREMENT UNITS The CEMQual program is independent of the units of measurement – usually ppm or mg/m3 for gas data. The program always uses the raw data stored by the analysers – contact Envirosoft should there be any doubt here. However, the measurement units do have an effect when entering the calibration gas data and the standard deviation information. The units of these items must match the stored analyser data, and may need to be adjusted. Figure 35 Parameter Saving And Copying CEMQual User Manaual v1.13 14/12/11 Page 34 of 71 DOC ID UM13 6.6 DETERMINING SPAN AND ZERO DELAY TIMES To determine the delay times for Span and zero, we first of all need to know two things; the date and time of a calibration audit, and the validity bit that is set during the audit. The easiest way of finding these is to use the Trend page in CEMForm (see below). In this example, the audit is carried out just before 07:30 on the 10th January, and the validity code 02 has been set. From section 6.6.1, we know that this is bit 2, and this parameter has to be entered in the QAL 3 parameter table (in this example, the same bit is set for Span and Zero, but with other instruments, they might be different for Span and Zero, and also different for each measurand). Figure 36 CEMForm CEMQual User Manaual v1.13 14/12/11 Page 35 of 71 DOC ID UM13 6.6.1 RAW DATA EXAMPLE The next step is to run a Raw Data report using CEMPort for the date in question, and scroll down to the start of the calibration audit, i.e. 07:23:39. We will see that the Validity code changes state – this will normally be from a 00 to the code seen on the Trend, but could potentially be non zero if the analyser has an invalid state, such as a fault or maintenance being carried out. We note the time that the audit begins and scroll down the report until we see each measurand stabilise its Span and Zero readings. In this example, both the NOx and the CO zeros settle out around zero some time around 07:25:00. By looking for a change in reading, as seen with the NOx channel below, we can choose a time somewhere between 07:25:00 and 0729:36, for QAL3 Zero points for each of the measurands. It is advisable to pick a time closer to the end of the zero phase of the audit, rather than the beginning, as this will ensure that the measurements have truly stabilised. Remember that we also have to average the readings for the “Span time” and “Zero time”, so this must be taken into account. So, in our example, we would probably take a zero reading for NOx and CO at 07:27:39 and average the readings for 30 seconds. This gives us a Zero delay of 240 seconds (07:27:39 - 07:23:39) and a Zero Time of 30 seconds. Tick the ‘Raw Data Report’ check box. Figure 38 CEMPort Figure 37 Raw Data 1 Figure 39 Raw Data 2 CEMQual User Manaual v1.13 14/12/11 Page 36 of 71 DOC ID UM13 Raw Data Example continued... Following the same method, we can determine the Span delay times for each measurand. NOx Span delay = 480 seconds; Span time = 30 seconds. (07:31:39 - 07:23:39) CO Span delay = 1140 seconds; Span time = 30 seconds. (07:42:39 - 07:23:39) Once these times have been established, they may be entered into the configuration table as described earlier in this section.

ELV (Emission Limit Value) refer to the site environmental permit. 2. Standard deviation values for span and zero assessments – Sams (Span) and Sams (Zero). 3. Zero and Span gas values. These values are only used in the QAL3 assessment should no gas bottle data be available for this measurand. 4. Confidence value; this data is currently not used by the program but will reflect the confidence as recognised by the authorities, these values are normally: CO (10%), NOx, SO2 (20%), dust (30%) etc. After the table is set up as required, press the ‘Save and apply’ button to store this data and apply it, should QAL3 data exist in the spreadsheet. Figure 42 CEMQual / EN 14181 CEMQual User Manaual v1.13 14/12/11 Page 38 of 71 DOC ID UM13 6.8 CALIBRATION GAS / REFERENCE DATA An important part of the QAL3 assessment process is to use the calibration gas data that was used as the reference material for each measurand at the time of each calibration check. This is performed in the Calibration gas data section; firstly click on a date in the “From date” column and press the “INS” Key on your keyboard. This should create a new row in the grid. Enter the date the bottle is first used, if it is a span gas enter True or Zero enter False, enter the value in mg/m3 and the bottle identifier. The latter is required to show a clear quality assurance chain. It is very important that this information is updated every time a gas bottle is changed or errors will be introduced into the calculations. To add a new bottle, select the latest date and press the INSERT key. Edit the new line as required and finish with the 'Save data' button below. Records may be deleted by pressing CTRL + DEL together - use caution. Although not essential, we recommend that the latest gas information is at the top of this list – it makes it easier to read. Once the gas data has been entered and saved, if data has already been collected for QAL3, the new reference data may be applied to the stored QAL3 information. To conduct this, press the ‘Apply’ button here. This will re-enter the span and zero gas data for all collected QAL3 data for the selected measurand. From date; Enter here the date from which the gas is to be used; it assumes that this will be used from midnight that day (00:00). During the automatic data find operation, the program will look up the appropriate verification gas to relate to the span reading found at the analyser. Span; Enter ‘true’ here if the gas entered is a SPAN gas as opposed to a zero gas; this is normally the case. Typically, as air or Nitrogen is normally used, there is only one entry for the zero data. Value; Enter true here if the gas entered is a SPAN gas as opposed to a zero gas; this is normally the case. Typically, as air or Nitrogen is normally used, there is only one entry for the zero data.

Figure 51 Manual Data Entry CUSUM Analysis CEMQual User Manaual v1.13 14/12/11 Page 44 of 71 DOC ID UM13 8 CONTROL CHART INFORMATION 8.1 CUSUM DRIFT CHART DETAILS CEMQual calculates the CUSUM drift information for both positive and negative drifts according to the European standard, EN 14181 (part C4). It operates on a set of data consisting of a series of check readings and reference levels (typically the analyser reading, and the gas bottle concentration). Two constants are calculated from the standard deviation (Sams) hx and kx. h x ??2.85 Sams (C.2) k x ??0.501 Sams (C.3) These values are used to test the QAL3 data. The difference between the recorded measurement and the reference is then calculated as: dt ??yt ??xt Where: yt = recorded measurement, xt = reference value The CUSUM check for positive drift is then calculated as: ?(pos)p ???(pos)t?1 ??dt ??kx (C.7) And the CUSUM check for negative drift calculated as: ?(neg)p ???(neg)t?1 ??dt ??kx (C.8) Effectively, should the readings remain in a band of +/- 0.501 Sams around the zero error line, the two CUSUM values will remain at zero. Should the readings exceed these values, however, the CUSUM will increase rapidly. It is compared against the value of hx for both positive and negative drifts. – if ?(pos)t ??hx , then a positive drift is detected; – if ?(neg)t ??hx , then a negative drift is detected. These constants are shown on CEMQual on the QAL3 page. These have been taken directly from the standard. CEMQual User Manaual v1.13 14/12/11 Page 45 of 71 DOC ID UM13 8.2 CUSUM DRIFT PASS / FAIL CRITERIA On the face of it, the CUSUM drift calculations may appear complex, and often produce a chart which remains on the zero line. However, the criteria for pass or fail is very easy to assess; the data must remain within +/- 2.85 x Sams. CEMQual plots the positive and negative drift values alongside their limit lines in RED (colour is selectable), and it is very easy to interpret whether the measurement system is in control or not. The above example indicates that the system went out of control for a period. Three items are checked – positive and negative drifts and the limit value. Should the data have been examined as a spreadsheet, the positive drift column over this period would have been highlighted in RED – normally GREEN. Figure 52 CUSUM Drift Pass / Fail CEMQual User Manaual v1.13 14/12/11 Page 46 of 71 DOC ID UM13 8.3 CUSUM PRECISION CHART DETAILS CEMQual calculates the CUSUM precision information for according to the European standard, EN 14181 (part C4). It operates on a set of data consisting of a series of check readings and reference levels (typically the analyser reading, and the gas bottle concentration). Two constants are calculated from the standard deviation (Sams) hs and ks. h s ??6.90 Sams (C.2) k s ??1.85 Sams (C.3) The differences between each subsequent check readings are made (d(t) and d(t-1)) for each of the readings in the data set. According to the standard, the following formula is used: ???? = ??(?? - 1) +(??(??) - ??(?? - 1))22- ???? And then compared against the hs value: if sp ??hs then a decrease in precision of the AMS has been established. NOTE: Effectively a band of +/- 1.85 x Sams exists around the data, and should the difference between the two consecutive readings remain in this band (according to the formula above) the Sp calculation will remain at zero constantly. The precision check is an indication of how much the calibration check data is varying by between each calibration, not an indication of absolute value. CEMQual User Manaual v1.13 14/12/11 Page 47 of 71 DOC ID UM13 8.4 CUSUM PRECISION PASS / FAIL CRITERIA To view a precision control chart, move to the Graph select box and click on the “CUSUM Precision” radio button; scale 2 is used for these charts. As long as the calculation of Sp remains under the precision limit, the measurement system meets the en14181 criteria for precision. In this example, the system has failed. Should a spreadsheet have been selected for viewing, the Sp column for the data will be highlighted in RED as below. Figure 53 CUSUM Precision Pass / Fail CEMQual User Manaual v1.13 14/12/11 Page 48 of 71 DOC ID UM13 8.5 SHEWHART CHART DETAILS To view a Shewhart control chart, move to the Graph select box and click on the “Shewhart” radio button. Although these charts ‘make sense’ to the operator by plotting each of the calibration checks directly against warning and alarm lines, their interpretation can differ. CEMQual uses the 5 parameters as detailed in the Environment Agencies Technical Guidance Note TGN-M20, and are, when: 1. One or more data points are beyond one of the upper alarm limits; 2. Three consecutive data points are beyond one of the warning limits; 3. Four points among 5 consecutive ones are beyond +/- Sams; 4. Eight consecutive points are on the same side of the mean; 5. Six consecutive points are either increasing or decreasing. NOTE: For condition 4 and 5, CEMQual will not indicate a failure if the data is within 0.501 x Sams. This avoids potentially ’silly’ failures that are possible when the recorded measurement is very close but consistently a little higher or lower than the reference. This agrees with the CUSUM check procedure (see page 44) which uses 0.501 x Sams as its ‘acceptable window’. Figure 54 Shewhart Details CEMQual User Manaual v1.13 14/12/11 Page 49 of 71 DOC ID UM13 8.6 SHEWHART CHART PASS / FAIL CRITERIA The warning limits are set at +/- 2 x Sams, and the alarm limits at +/- 3 x Sams. These are drawn on the chart as illustrated above, and are usually coloured in orange and red as seen here. These colours may be changed by the operator if required. The interpretation of the data for the above 5 conditions is displayed on the chart area as a series of coloured blocks – one for each measurement. Normally these blocks are GREEN when none of the criteria have been breached, but this will turn to RED should one or more conditions be breached. The example here shows three failure conditions, from left to right: one or more point beyond the alarm, three or more consecutive points beyond the warning, and 6 consecutive points either increasing or decreasing. Although CEMQual will check for a pass/ fail automatically, it can be seen that the interpretation of this is not as straight forward as the CUSUM drift procedure detailed earlier. There appears to be a tendency for the UK to use Shewhart charts rather than CUSUM charts for drift. According to the European standard, however, the opposite is true. Ultimately, however, it is up to the operator and their EA representative to decide which chart to use. NOTE: The Shewhart chart does not check on the precision of the measurement system. CEMQual User Manaual v1.13 14/12/11 Page 50 of 71 DOC ID UM13 8.7 EWMA CHART DETAILS The exponentially weighted moving average (EWMA) charts were offered as an acceptable alternative to CUSUM or Shewhart charts for drift assessment in the European document: CEN/TR 15983. Effectively, this calculation biases the result data according to historic data more than the effect of each individual check. One factor controls this bias, l, and subsequent readings are analysed by: New EWMA = (1 – l) x Old EWMA + l New Reading NOTE: For the first average, EWMA = New Reading. This formula is as stated in the document referenced above, however, it only works for a constant reference value; a change in reference will see a step change that may well result in an error. To accommodate this likelihood, CEMQual uses the errors between the reading and reference, rather than the absolute value. This has been tested with the suggested information in the standard and the same results produced. This bias value is selectable, but the following is suggested: l = 0.35 Or, about two to one in favour of the old data compared to the new. If l nears 0, this will take the past more into account and detect small drifts, but sudden major drifts are less easily detected. If l nears 1, this will take the past less into account and responsiveness to sudden major drifts are greater, but small drifts will be less easily detected. The calculated EWMA is then compared against thresholds set at a suggested level of: +/ - 2.9445 x Sams v(l/ (2 – l)), When using 0.35, we get: +/- 1.38 x Sams for drift limits. CEMQual User Manaual v1.13 14/12/11 Page 51 of 71 DOC ID UM13 8.8 EWMA PASS / FAIL CRITERIA In a similar fashion to the CUSUM drift check procedure, the EWMA is easily assessed; it must remain within the two limit values. The example here indicates that the measurement system is within control for drift when assessed using the EWMA method.

EN 14181, QAL3 analysis considers two different checks on the measurement system: drift and precision. The check for complying with drift may be conducted using either: 1. CUSUM for Drift method, as defined within EN 14181 – Stationary source emissions – Quality assurnance of automated measuring systems. 2. Shewhart charts, as defined in UK EA M20 document – Quality assurance of continous emission monitoring systems application of BS EN 14181 and BS EN 13284-2. 3. Exponentially weighted moving averages (EWMA) as defined in FprCEN/TR 15983 – Stationary source emissions – Guidance on the application of EN 14181:2004. Any method appears to be acceptable and may depend on the local inspectorate as to which is preferred. CEMQual can conduct all of these analysis types if required. Only one check is dicussed for precision analysis and this is the CUSUM method in EN 14181. CEMQual conducts this if required and can plot the data with limits. For record keeping, it is advised that at least the spreadsheet view is printed – this will display the raw data and also demonstrate compliance with all of the above checks. CEMQual User Manaual v1.13 14/12/11 Page 54 of 71 DOC ID UM13 10 IGNORING ERRONEOUS READINGS For many reasons, the results of QAL3 for a particular day may be in error – e.g. the gas bottle was empty or the analyser aborted the calibration half way through. CEMQual provides three ways of ignoring this data, please note however, that data from the CEMSuite database is never deleted, it is only the QAL3 analysis that is affected. The three methods of ignoring the QAL3 data are: 1. For temporary exclusion – uncheck the box from the spreadsheet view of the data. The QAL3 analysis will re-appear every time the same selection is made again. 2. Semi-permanent exclusion – Enter the text “*** NO QAL3” within the comments. This will cause this record to be ignored every time the data is recalled or re-analysed. Effectively any calibration from the same date and time (nearest minute) will always be ignored from this measurment group. 3. Permanent exclusion – For permanant exclusion of data, the records for the day should be deleted from the ‘Advanced page’ - see page 60. Records here will only re-appear after this data has been re-analysed.

The ‘Print all’ function here will print all required measurands (as selected from the QAL3 parameters table) for zero and or span as selected. To change the printer CEMQual uses, high-light it in the list and press the ‘Set as default’ button. This printer will now be used by CEMQual until this setting is changed. Note, should printers be added or removed after this operation, CEMQual might revert to another printer by default. It is advisable to redefine the default printer if any changes have been made. NOTE: The printer orientations are fixed; portrait for spreadsheets and landscape for Graphs.

However, in order to avoid the use of a computer at the measuring site, manual calculations may be performed on site. A sheet, as given in annex H, can be very helpful for those calculations. At the same time the sheet can be used for documentation of the documentation of the AMS (see clause 9). This procedure has to be performed at each reading of the zero and span values from the AMS. Calculate the provisional sum for standard deviation, and the provisional sums for positive and negative difference. ???? = ??(?? - 1) +( ( ) ( )) - ???? (C.6) S(pos)p = S(pos)t-1 + dt - kx (C.7) S(neg)p = S(neg)t-1 - dt - kx (C.8) Where dt = yt – xt and is the difference between the actual instrument reading and the reference value; notice the sign p indicates the provisional value of the normalised sums t indicates the actual instrument reading t - 1 indicates the previous instrument reading Calculate the test values, and add up the number of instrument readings since the standard deviation and the (positive or negative) difference occurred as follows: Precision check ? If sp > 0 : st = sp And N(s)t = N(s)t-1 + 1 If sp <= 0 : st = 0 And N(s)t = 0 Positive and negative drift checks ? If S(pos)p > 0 : S(pos) = S(pos)p t And N(pos)t = N(pos)t-1 + 1 If S(pos)p <= 0 : S(pos) = 0 t And (pos) = 0 N t ? If S(neg)p > 0 : S(neg) = S(neg)p t and N(neg)t = N(neg)t-1 + 1 If S(neg)p <= 0 : S(neg) = 0 t and (neg) = 0 N t CEMQual User Manaual v1.13 14/12/11 Page 65 of 71 DOC ID UM13 15.2 C.5 TEST FOR A DECREASE OF PRECISION Test the precision of the AMS: – if st > hs then a decrease in precision of the AMS has been established. If this inequality is false for both zero and span precision then these components of the AMS are in control, and the test for zero and span drift shall be performed. However, if the above inequality is true for either zero or span precision, the manufacturer shall be contacted. In this latter case it is unnecessary to perform the drift tests at this time. 15.3 C.6 TEST FOR DRIFT AND THE NEED FOR ADJUSTMENT Test for positive or negative drift of the AMS: – if S(pos)t > hx , then a positive drift is detected; – if S(neg)t > hx , then a negative drift is detected. If both of the two inequalities above are false for both zero and span, then the AMS is in control and no action is required. However, if one value is true for either zero or span, then an adjustment of the AMS is required, and thereafter the calculations continue from C.2.
