photo detector LCD display range select buttonturn off, turn on, value hold
Connect the battery, and then press the button to ON Press the range selection switch to desired range.Remove the photo detector cap and face it to light source in a horizontal position.Read the test value from the LCD display.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.Data-Hold mode: press the HOLD key to select Hold model. When HOLD mode is selected, the LUX meter stops all further measurements and the test value with hold on the LCD. Press the button HOLD to the ON , the hold value will be cancelled.
When the measurement is completed, replace the photo detector cap and turn the power selector OFF
BATTERY CHECK-UP & REPLACEMENT:
It is necessary to replace another one 9V battery, when left corner of LCD display show .After turning off the meter, press the battery cover and push in the direction of the arrow to open.Disconnect the batter from the instrument and replace it with a standard 9-volt transistor battery and go for the cover.
The white plastic disc on the top of the detector should be cleaned with a damp cloth when necessary.
Do not store the instrument where temperature or humidity is excessively high.
The reference level, as marker on the face plate, is the tiof thep photo detector globe.
The calibration interval for the photo detector will vary according to operational conditions, but generally the sensitivity decreases in direct proportion to the product of luminous intensity by the operational time. In order to maintain the basic accuracy of the instrument, periodic calibration is recommended.
