3. PANELDESCRIPTION

1. LCD display: 3 – 1/2digit LCD display with low battery

“BAT” 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.OPERATING INSTRUCTION

Measuring Light

1. Turn the Power/function/range Switch to select the “lux” scale

and set the range to desired (“lux”, “x10 lux” or x 100 lux)

range.

2. Remove the photo detector to light source in a horizontal

position.

3. Read the illuminance nominal from the LCD display.

4. Over-range: If the instrument only display 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 (λ) as the following chart

described.

If the sign “BAT” appears on the LCD display, it indicates that

the battery should be replaced. Remove screws on the back cover

and open the case. Replace the exhausted battery with new

battery.
