Special functions-optical power meter

optical power meter provides three modes, i.e.: factory mode, user mode and working mode, it usually enters working mode.

Factory mode

The measurement and calibration are made by the factory.

User mode

Press λ+Light together, the system will enter user mode, and the “nm” at the end of the first line will be absent. Press λ+Light together again, the system will exit user mode and enter working mode, the “nm” at the end of the first line will appear again.

10 minutes’ auto off

Press AUTOOFF to enable AUTO OFF function, the icon “OFF” will appear on the left top of the screen, then the meter will automatically turn off if there are no operations within 10 minutes.

LED backlight ON/OFF

While in working mode, press LIGHT to turn on backlight, the symbol “a little sun” will appear on the left top of the screen indicating backlight is on.

Serial port commissioning

Connect serial port plug to PC’s serial port, you can access data and calibrate the meter (see the Figure on the right) via PC.


While in normal working, the power volume indicator will not appear in the screen; however, when the battery is going to run out, the power volume indicator will blink once a second, the meter will automatically power off after the indicator blinks for ten times; if so, you can insert the meter into supplied charger for charging (see the Figure on the right), this way saves a lot of trouble and cost in replacing battery.
