-
REF/dB key: Short press the dB unit to switch, long press until the screen displays REF to enter the relative optical power test mode
-
LED light switch key: turn on/off the flashlight, press any key to turn on the backlight
2 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.
3 Power reference value setting
- 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.
- 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
4 Optical power wavelength switching
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.
5 LED flashlight
Flashlight switch: Short press the “ ” button to turn on the flashlight, which is convenient for use in a dark environment and realize the lighting function; short press the “ ” button to turn off the flashlight.
6 Calibration function description
Press REF/dB first, and then press the +REF/dB keys simultaneously to enter the calibration mode. The λ key is to adjust the value down, a nd the REF/dB key is to adjust the value up. Press the power button to save the value and exit the calibration procedure.
| Key | Function |
|---|---|
| REF/dB | Increased by 0.1dB |
| λ | Reduced by 0.1dB |
| save |
7 Product description
This product uses a 650nm semiconductor laser as a light-emitting 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.
