On the optical power meter
interface, short press the "λ" key to
switch the measurement wavelength.
You can choose 7 different test
wavelengths, 850nm/980nm/1300nm/
1310nm/1490nm/1550nm, 850nm,
1625nm. To ensure the accuracy of the
test, the selected wavelength must be
consistent with the wavelength of the
measured optical signal

Enter the optical power meter
interface after booting, short press the
"REF" key to set the current power value as
the reference power, which can realize
relative optical power test (insertion loss
test) or absolute power test. After entering
the relative power test mode, the insertion

loss (dB) is displayed at the bottom of the
screen, and the screen displays the
reference value; short press the "dB" key to
switch between linear power and absolute
power display.
The units of linear power, absolute
power, and relative power are W, dBm,
and dB respectively.
P absolute power = 10lgP linear power /
1mW.
P relative power = P absolute power-P
reference power.
