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.

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.
