Operation Instructions

1. Power On/Off and Auto-off Function

Press        button to turn on the instrument, then press for 2 seconds or longer to turn off.

This multimeter has a power-saving function. If 10 minutes without any operation, the 

instrument will automatically shut down. If you need to shield this function and enable 

the multimeter keep on working, only need to press        button and hold on when you 

boot the meter. After 2 seconds, the instrument will display       which means permanent  

power on.

2. Backlight Function

When the instrument is powered on, short press        button to turn on/off backlight. The 

backlight function support you to use the multimeter at night or darker occasions, and 

you can set level 0-9. If seting as 0, backlight off, and no backlight even press button.

3. Menu Setting

Press        button to switch each setting interface, then press        or        button to modify 

the specification. If all finished, press for 2 seconds to exit Menu setting.

4. OPM - Select Wavelength

According to the project's demand, we need to measure optical signals of different 

wavelengths. Then we need to select a corresponding wavelength to measure the 

optical power. If the measured wavelength is different from the wavelength we selected 

on OPM, it will lead to the measuring values meaningless.

After turning on, press       button to switch OPM wavelength from 850nm, 1300nm, 

1310nm, 1490nm, 1550nm, 1625nm.

5. OPM - Data Storage/Query

On the OPM interface, long press        button, the display will show "SAVE" and storage 

number at the top left of the screen and will flash together 3 times. At the same

time, the display will show the current stored power value on the screen. After 2 

seconds, the multimeter will restore the measuring interface, and save the current 

measurements in the instrument.

The multimeter can store 1000 records. Each storage number automatically increases

one by one, if over the limit, the first data will be overwritten and so on.

On the measuring interface, short press        button to data-saving interface, you can
