Please read the manual carefully for proper operation and best function of this device prior to using. REFACE Illumination: The flux of light received in a unit area of a certain side being shone is popularly known as illumination. In both United Kingdom and America its unit is known as foot candlelight, but in Europe it is known as meter candlelight. One foot candlelight is the illumination of light which falls on one side that lies in a distance one foot away from a one foot candlelight and exactly intersecting the light. Its abbreviated form is written as 1 Fc=1 Lm/ft, Similarly, one meter candlelight is the illumination of light which falls on a side that lies in a distance one meter away from a one meter candlelight and exactly intersects the light. lt is also called Lux i,e. the flux of light being receivedin each sq. meter is called the illumination of one lumen. As one foot candle=10.76 Lux, therefore, Nbr. of foot (meter) candlelight= Nbr. of Lumen -------------Area(sq. foot or sq. meter) Nbr. of Lumen=Nbr. of foot (or meter)x area (sq, foot or sq. Meter) `I .FEATURES Silicon Photodiodes Features: For visible Light Spectral Response Range Mark (nm): 320-7301E 80E 8) Disassembling method ofthe battery: 1. Make the screw loose first and push the battery cover back. 2. Then the battery cover can be seperated the meter. 4. PANEL DISPOSITION. 1). SENSOR Input connector: The sensor test input terminal. 2). Display(LCD): Display measurements and function symbols. 3). 0 ADJ: If any digits appear in the LCD display. Then ADJ is indicated and the zero adjustment for all ranges is performed at the samtime. 4}. D-H switch: Touch D-H the meter captures a stable measurement and holds it in the display.(Fig.1) 5). LuxlFc Switch: For selecting switch Lux and Fc. 6). MAX: Lock up max, value of LCD. 7). POWER Switch: ON/OFF switching. 8). Range Selection switch: For selecting various ranges(resolutions). 2. SPECIFICATIONS 1) Indication: 3112 digit LCD with Maximun indication value 1999. 2) Overload indication: Indicated by "OL" at the highest position on the left lateral side. 3) Low battery indication: when"~"is indicated by the LCD indicator, lt means that the battery should be renewed. 4) Battery life: Approximately 200 hours. • Peak Wavelength (nm): 560 • Silicon Diode light receiving wave is found to long and extensive in area. • Testing: Lux and Fc are available for selection. • Ranges for Lux: 200, 2000, 20000, 50000 Lux. Fc: 20, 200, 2000, 5000 Fc. • Testing Range: Lux from 0.1 --100000 Lux. Fc from 0.01 -.10000 Fc. • With DATE HOLD function which allows testing indication value to be fixed at will. • Large size LCD indication, featured for low battery indication function. • MAX function: Hold the maximun value on the LCD indication. • RANGE funtion: range touch selector. • LuxlFc function: For selsction of Lux or Fc. • POWER Function:For power on and off. • CLASS: Conforms to JIS C 1609 - 1993 general A dass. • Spectral Response 3. OPERATION PROCEDURE 1) Open the carrying case. 2) Turn on the Power Switch. Choose the unit of Lux of Fc which you want to test. Then choose the right range appropriate for testing. 3) Remove the cover of the light receiver, Put the light receiver at the spot where the testing of source of light is to be conducted, Auto testing will then be conducted by the meter, Read the testing value after the reading indicated becomes stable. 4) when "OL" is shown at the highest position at the left lateral side, overload is indicated, Then please choose another range which is located at a comparatively higher position. Attention: when testing is fixed at the range of 20000Lux,50000Lux,5000Fc,the numencal value shown by the indicator must be multiplied by 10 times or 100 times to get the true value tested. 5) If you want to keep the reading value on the LCD permanently after testing, press the D-H Key whereby the reading value will be locked permanently up. Press the D-H Key once again when you want to remove the previous locking. 6) After testing, put the cover of the light receiver back to its former position, and turn off the switch. 7)After testing is completed, the indication value should be 000 no matter what its range would be after putting the cover of the light receiver back to its former position. Please adjust 0 ADJ to enable LCD to indicate 000 if zero cannot be recover. If zero still can not be recovered, lt means that the meter breaks down. 5. ATTENTION 1)In the measurement of illumination, the reading will be caused to jump by the variance of power or the shadow of surrounding people. The condition of the surrounding temperature, air current and ventilation will also cause the source of light to vary. 2)When the source of light is received too early by the light receiver, the precision of the mefer will be reduced. Always keep the cover of the light receiver in its place. Avoid to allow the light receiver to be come overloaded or avoid to mput high source of light when testing is being conducted at low illumination. 3)The mark set for referencing the testing of source of light is located at the right top end of the light recieving ball plane. 4)When the meter is turned on and the light receiver cover is put in its place, 000 should be indicated by LCD, However, if the voltage of the battery varied and the low battery sign"ö" is still not yet indicated it, will easily prevent zero from being recovered when the meter is being switched on 0 ADJ should then be adjusted to turn lt back to zero be fore measurement should be started. 5)When low battery sign"~"is indicated, the batteries should be renewed.lf zero cannot be recovered after the battery has been renewed, Please adjust 0 Addition so as recover zero. 6)When the meter is not in use, please keep the cover of the light receiver in its place to avoid the sensor from wearing out. 7)When it is not in use for a bong time, please take the batteries away. And avoid to keep lt in a place of high temperature and humidity.
