3 in 1 Function:Optical power meter built-in 15MW Visual Fault Locator (VFL) & LED Lighting.
Advantages: If there is no operation for 10 minutes, the device will automatically shut down; Save electricity, 500 sets of data memory; Wavelength memory, optical power testing error less than 0.2dB; Users can independently calibrate data.
10 standard measurement wavelengths: 850/980/1270/1300/1310/1490/1550/1577/1625/1650nm, testing range: -70dBm to+10dBm.
Interface: 2.5mm universal interface, with a wide range of applications, supporting SC/FC/ST/three common interfaces, LC interface requires the use of FC-LC adapter.
User calibration: Press and hold the power button while shutting down the device+ λ Press the wavelength button for 2 seconds, and after turning on, enter the calibration function interface (REF button: increase 0.1dB/dB button: decrease 0.1dB)
