is displayed and the last reading is hold on the display.
5.2 Operation Mode
1. Set the ON/OFF/HOLD key to the ON position to turn
on the instrument.
2. Set the RANGE key to the desired range.
3. Remove the protective cover of photosensor and
place it in horizontal position.
4. Keep a safe distance of the sensor to prevent
shadows over the sensor. The sensor is connected
to the instrument by 1.5m cable that allows the
separation between the user and the place of the
measurement.
5. Read the measured value in the display.Ifthe display
indicate "1" means that the measurement exceeded
the range, and it is necessary to change for a higher
range. In 100000lux range, OVER is indicated as
over range.
6. When finishing the measurements cover the
photosensor to protect it and turn off the instrument
setting the ON/OFF/HOLD key to OFF position.
