OPERATION
MEASURING THE LIGHT (LUX)
1. Turn the power/function/range switch to select the "lux" scale and set the range to the desired
("lux" or "x10 lux") range.
2. Remove the meter and face the photo detector to lthe ight source in a horizontal position.
3. Read the illuminance nominal from the LCD display.
4. Over-range: If the instrument only displays one "1" in the M.S.D. the input signal is too strong, and a
higher range should be selected.
5. When the measurement is completed, replace the photo detector from the light source.
6. Spectral sensitivity characteristic: To the detector, the applied photo diode with filters makes the
spectral sensitivity.
