Its cylinder shaped case hosts a battery and electronic circuits (including realtime generator) that provides digital measuring and recording of temperature. This reader is water-proof and it can be submerged in non-aggressive liquids. A probe reads and records the temperature of the surrounding environment. The probe is initialized by a personal computer through an adapter - it is used to program operation initiation time, type and title of operation, notes, etc. The probe is then inserted into the monitored environment where it operates independently, measuring and recording temperature. When finished, the probe is connected to a PC that reads the measured data for further processing. The probe may operate in one-shot mode, when the data reading is initiated at a set time and when the probe capacity is full, the reading terminates automatically. The other operation mode is periodic reading, when the oldest data is overwritten by new values once the probe reaches its full capacity.The main advantage of this reader is that it involves no cables and connectors and therefore it can be transported in sample containers during transport. This provides complete sample temperature (as opposed to environment temperature) account since the sample taking until the beginning of laboratory analyses.QHTemp temperature reader meets CSN EN 12830 standard requirements and thus it can be used anywhere where temperature time behavior must be monitored, especially during storage and transportation of food, medications, and other temperature sensitive material. In the data overwrite mode the QHTemp reader can be used as a black box for long-term monitoring of the temperature of e.g. coolers and freezers, stores, truck containers, packages, etc.ApplicationMake sure the reader temperature does not exceed 80°C while in operation Having programmed the required features, put the reader into the environment to be monitored. The unit is waterproof and designed to be submerged in non-aggressive liquids. If you wish to monitor a surface temperature, attach the probe’s metal face (with no dent on its perimeter) to the material to be monitored using silicon Vaseline. When measuring environment temperature, use the socket holder located in a suitable place. When installing, take into account that the temperature sensor measures the environment temperature through the metal face with no dent on its perimeter The sensor can be in any position. Before you place the QHTemp reader into the USB adapter, make sure it is clean and dryThe reader body is made of PVC-U and stainless steel. Do not use cleaning solvents that might damage these materials.denttemperature sensorManufacturer codeHW versionDate of production yy/mm/ddSerial numberHW version Control codeSoftware installation and useThe control software can only be installed in computers running WindowsTM 95/98/ME/2000/XP equipped with a USB interface.1. insert the supplied install CD in the CD drive and wait for autorun2. follow on-screen instruction to install the software3. do not remove the CD from the drive and connect the QHTemp USB adapter to the computer 4. follow on-screen instruction to install USB adapter drivers from the CDAfter successful installation and running of program, the connected adapter will be displayed on the lower toolbar.USB adapter communication control light, it blinks simultaneously with the LED on the adapter adapter connection statusWorking with the probeConnect the reader adapter to standard USB computer interface. If the adapter registers correctly, the control LED blinks shortly. Run QHTemp software. The bottom status line of the program displays the name and serial number of the adapter. Insert the probe in the adapter. The program recognizes the probe automatically and it reads basic information regarding its status. You may establish the probe status repeatedly using menu command Probe/Read data. After status reading, the form with probe information displays automatically. If the probe still reads data, it can be interrupted using Probe/Stop command. Unless the probe is in Memory erased status, the data collected by the probe can be read with command Probe/Read data.If you need to erase the probe contents, use the command Probe/Erase. Erased probe can be run using the command Probe/Start . The probe will start operation at a time specified in the field First sample.NOTE: First step with NEW probe – use command PROBE/ERASE for ON.Working with filesThe probe status and collected data can be stored on the computer disc. Use options File/Save and File/Save as. Saved data can later be opened using File/Open command. Data saved on the computer disc will be loaded into QHTemp program and it can be viewed using commands from View menu. Having viewed the file, you may continue working with the connected probe by selecting File/New.Probe statusChoose View/Status command. The form contains the following data:Serial number : probe serial numberName : probe name assigned by the userCommentary : commentary edited by the user into the probe Probe clock : current probe clock settingComputer clock : current computer clock settingReading start : time of start commandFirst sample : time of first sample takingReading time : time of last temperature contents readingSampling period: time interval between two samples in minutesTotal samples : total number of samples taken since probe deliverySampling in progress: the probe takes samplesMemory erased : the probe is idle, all data are erasedOverwrite enabled : periodic data overwriting in case of capacity exceeding enabledOverwritten: data in the probe was periodically overwrittenIf the probe contents are erased, you may edit fields Name, Commentary, First sample, Sampling period and Overwrite enabled. Click the Write texts button to write fields Name and Commentary into the probe. This operation may take a while. Other data are written in the probe the moment it starts. Click Set clock button to synchronize internal probe clock with the computer clock. Click As soon as possible to set the time in the First sample field on the closest minute. The probe must be started immediately after this setting takes place.NOTE: probe reading cannot be resumed if it was stopped. Before editing and re-running, the probe contents must be erased. Having stopped reading, do not forget to load and save the contents of the stopped probe. You do not have to stop the probe to load the data from the probe while it takes reading.Measured data tableDisplay the table by clicking View/Table.The table contains all values – samples taken by the probe as pairs Date/Timeand Temperature.Measured values graphClick View/Graph to display the graph. The graph shows taken temperature in time.Use Disable 3D to redraw the graph in technical style without 3D.Use Date field to display the date on the time axis. Clock is displayed always. The scale of time axis can be selected in the upper right corner. Maximum option displays all probe readings. 24h or 1h displays 24h or 1h readings in one graph. You may move in the graph using buttons that appear to right of the graph title. The graph may also be moved by clicking and holding the left mouse button inside the graph and moving it. The scale on the vertcal axis (temperature) is selected by the program automatically so that all measured values are displayed appropriately.Measured values histogramClick View/Histogram to display the histogram, Histogram is a column graph representing the relation between the number of samples and the temperature. One column represents the number of samples taken in 2°C range. Use Disable 3D field to redraw the graph in technical style. The scales of graph axes are selected automatically to provide for all measured values.Exporting measured valuesThe program makes it possible to save the values loaded from the probe on the computer disc in a format suitable for other programs (such as MS Excel). Use menu command File/Export.Printing measured valuesData loaded from the probe can be printed as a standard form, containing basic information concerning the probe, and the graph with measured values.
