Operating Instructions
Measuring Light
1. Turn the Power/Function/Range switch to select the range to desired
(x1 Lux/Fc , x10Lux/Fc, x100Lux/Fc) range.
2. Remove the photo detector to the light 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 characteristic almost
meet C.I.E. (International Commission on Illumination) photopia curve
V( ) as the following chart described.
