REF/dB key: Short press the dB unit to switch, press uW/dBm/
dB once to enter the last cleared data, long press until the
screen displays REF, set the current optical power as the
reference value, and enter the relative optical power test mode.
The display will show the reference value that set before.
After short press the power button,
the meter will turn on and automatically
start the automatic shutdown function.
The default automatic shutdown time is
10 minutes. To cancel this function, press
and hold the power button when the power
is turned on. When the power button dis-
appears, the automatic shutdown will be
canceled.
P absolute power = 10lgP linear power / 1mW
P relative power = P absolute power-

Insert the fiber which is under test
into the OPM interface.After booting, enter
the optical power meter interface, short
press the "REF" key to set the current
power value as the reference power, which
can achieve relative optical power test
(insertion loss test) or absolute power test,
enter the relative power test mode at the
bottom of the screen Display insertion
loss (dB).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 nW, dBm, and
dB respectively.
Insert the fiber under test into the
VFL interface, press the VFL key to enter
the VFL test interface.
On the optical power meter interface,
short press the "λ" key to switch the
measurement wavelength, select 7 different
test wavelengths, 850nm/980nm/1300nm/
1310nm/1490nm/1550nm, 850nm, 1625nm
to ensure the accuracy of the test, select
the wavelength should be consistent
with the wavelength of the measured
optical signal.
