Description of the unit

1. Photo detector: long life silicon photo diode inside
2. MAX and LUX/Fc function button: Press button quickly, the max reading will be displayed. Pressing it once again will release the hold and allow another measurement. Pressing this function button for 2 seconds will change the display between LUX and Fc.
3. Power: Turn power ON or OFF.
4. LCD Backlight Control: Meter will be will sensitive to environment light intensity, if the environment is dark, it will turn on the LCD backlight on automatically, otherwise it will turn off the LCD backlight.
5. Auto-ranging: x10 means the meter is in range 20k Lux, and the readings should multiple with 10; x100 means the meter is in range 40k Lux, and the readings should multiple with 100.
6. LCD display: 1999 counts LCD display with LUX, fc, MAX, indication
7. MAX: The highest reading is displayed on the display.
8.  Low battery indicator
9. Battery cover

Start-up the unit
Insert the battery
Open the battery cover and insert the 9 volt battery according to the correct polarity.
Power
Press the power button to start normal measurement.
Automatic Power OFF
Meter automatically shuts down after approx. 30 minutes of inactivity (Sleep Mode). To override Auto Power Off function (Non-Sleep Mode), firstly press the MAX/MIN button and hold, then press power button, after the display appears, release both buttons. Icon “ ” will not shown on the LCD. The unit will not auto power off now.
Measurement

1. Remove the photo detector to light source in a horizontal position.
2. Read the luminance on the LCD display. If the environment is dark, the LCD backlight will automatically turn on.
3. The measure range will changed automatically with the light intensity. It includes 200.0 Lux,2000 Lux,20 Klux and 40 Klux 4 ranges for Lux; or 20.0 FC,200 FC,2000 FC,4000 FC 4 ranges for FC correspondingly.
4. Press the function button for about 2 second to change the unit between Lux and Fc
5. Press the function button quickly to change to the MAX HOLD function. Press once again to release the hold and allow another measurement.
6. Over-range: If the instrument display “OL” in the M.S.D. the input signal is too strong
7.  When the measurement is finished, replace the photo detector from the light source.
8. Spectral characteristics of sensitivity: The photo diode with filters applied to the spectral sensitivity does meet CIE (Inter national Commission on Illumination) photopia curve V (ʎ) describes.
9. If it appears, battery should be replaced with new one.
