Panel Description
1- LCD display: 1999 counts LCD display with
LUX, Fc, LOBAT, MAX, HOLD indication
2- Power /Function/Range switch: Turn power ON or OFF
and select measurement function and ranges. 3- Photo Detector: Long life silicon photo diode inside 4- MAX. HOLD: If you press the MAX. button, the maximum reading
will be held. Pressing the button once again, will release the hold and
allow a further measurement. 5- DATA HOLD: The reading will be held when the Data Hold button
Switch is pressed. If the button Switch is pressed once again,
it will release the hold and allow a further measurement. 6- Function button: Selects measurement functions of Lux or Fc

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  lters makes the spectral sensitivity characteristic almost meet C.I.E. (International Commission on Illumination) photopia curve
