Power/Off button
Short press the power button to turn on
the meter. The meter has automatic
startup and automatic shutdown functions.
The default automatic shutdown time is 15
minutes. If you want to cancel this function,
press and hold the power button when it is
turned on. After turning it on, the " " icon
on the screen disappears, indicating that
the automatic shutdown is canceled.
Power reference value setting
1.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.The
insertion loss (dB) is displayed, and the screen
displays the reference value; short press the
"dB" key to switch between linear power and
absolute power display.
2.The units of linear power, absolute power,
and relative power are nW, dBm, and dB
respectively.
P absolute power = 10lgP linear power / 1mW
P relative power = P absolute power-
P reference power
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 Must be
consistent with the wavelength of the measured
optical signal.

This product uses a 650nm semiconductor laser as a light-emit-
ting device and is driven by a constant current source to emit a
stable red light; it enters a single-mode or multi-mode fiber after
being connected to an optical fiber interface to realize the
function of fiber fault detection. It is an optical fiber engineering
construction and optical fiber network. An indispensable tool for
maintenance, optical device production and research.
