:Power key, turn on/off automatic shutdown function
/VFL: turn on/off back light, turn on/off VFL- RJ45/dB: turn on/off RJ45 sequence, switch absolute power display
- RJ45 network port: RJ45 sequence/tracking test
- PRESS button: press to take out the RJ45 sequence remote tester
- Remote tester: RJ45 cable sequence test
- λ: switch the test wavelength of the power meter
- LED key: turn on/off flash light

Power on/off and automatic shutdown
After pressing briefly, the meter will turn on and start the automatic shutdown function. The default automatic shutdown time is 10 minutes. If you want to cancel the function, press and hold the power key for two seconds, and the icon dis appears, the automatic shutdown will be cancelled.
Set Reference Optical Power 
After power on, enter the interface of OPM, press REF to set the current power as the reference power, switch the relative optical power test (insertion losstest) and absolute power test. In the relative power test mode, the insertion loss (dB) and the reference value is displayed simultaneously. Short press “dB” to switch linear power and absolute power display. The units of linear power, absolute power and relative power are W, dBm and dB respectively.
Pabs.p=10lglin.p/1mW
Prel.p=Pabs.p-Pref.p
Switch the Wavelength 
In the interface of OPM, short press the λ key to switch the measurement wavelength. Ten different wavelengths can be selected: 1310nm, 1550nm, 1577nm, 1490nm, 1625nm, 1650nm, 850nm, 1270nm, 1300nm and 980nm. In order to ensure the accuracy of the test, the selected wavelength must be consistent with the measured optical signal.
RJ45 Cable Sequence and Analog Cable Tracking 
In the test interface of OPM, long press the dB key to display the word “RJ45” on the screen. At this time, enter the RJ45 cable sequence test, connect one end of the network cable to the RJ45 port in the bottom, and connect the other end to the remote tester. Short press the dB key to exit. Long press the dB key again, “ ”displays on the upper left corner of the screen, enter the cable tracking mode, and short press the dB key to exit.
VFL and LED flashlight 
After power on, long press the /VFL key to turn on the VFL, short press to flash and turn off.
Press the power button to control the flashlight turn on and off.
Calibration instructions
At the same time, press the LED+REF key to clear the user’s calibration value, and the screen will full display “-” to restore default value; press the LED+VFL to enter the calibration mode, and “Cal” will be displayed in the upper left corner of the screen. The following operations are only valid in the calibration mode.
