G11 Optical Power Meter FC/SC/ST Universal Port Fiber Optical Power Meter Tool Description: Wavelength range: 800-1700 Probe type: InGaAs Measuring Range: -70~+6dbm, -70~+10dbm, -50~+36dbm Tolearance +5% Standard wavelength: 850/980/1270/1300/1310/1490/1550/1577/1625 Display resolution: Logarithmic display-0.01dBm, Linear display-0.1% Frequency distinguished(HZ): 270.1000.2000 Static current: 18uA Working Current: 25mA Endurance time: 20H Charging Voltage: 5V Charging Current: 500mA Charging Time: 3H Automatic shutdown time: 10min Power: Rechargeable Lion battery Battery: 400mAh size: 172x40x28mm Specific: 1, High precision 2, USB Fast charging 3, 9 Kinds of Wavelength 4, LED light 5, Universal Connection 6, Automatic calibration 7, Memory wavelength 8, Frequency distinguished How to calibrate? 1, Press Power button at the same time. It will show Cal in the third row to enter User calibration mode. Currently press power button+0.05dbm, press Fn-0.05dbm. 2, When you finished user calibration, A: press power button a little longer time to shutdown to save calibration data. B: press power button+Fn to exit to save calibration data. 3, Press Fn a little longer time and press power button shorter time twice, then Light fading DB data will come to zero. 4, Press Fn a little longer time and press power button shorter time once, light fading Unit switching. How to restore factory data? Press Fn a little longer time and press power button shorter time for 3 times, it will be factory data reset. Then the display screen will be light and the machine will restart. Package included: 1x optical power meter 1xUSB charging cable 1x Manual 1x lanyard
