How to use1. Press the power button and "dBm" button at the same time, the instrument enters manual calibration mode (the four rows of units are displayed at this time)2. Select the calibration wavelength with "λ", press "REF" to increase by 0.05 dB each time, and "dB/W" to decrease the power value by 0.05 dB 3. Short press the power button to save the calibration data4. Press the power button and "REF" button at the same time to exit calibration mode.Package List1 x Optical Power Meter (battery not included)1 x Adapter Head1 x Storage Bag1 x Manual TL510 Optical Power Meter Measuring Instrument High Precision Optical Power Detector 70~+10dBm Item Type: Optical TesterMaterial: Plastic PlasticProduct Model: TL510dBm Measurement Range: -70~ +10 dBm (the best actual measurement range is -65 ~ 0dBm)Wavelength range (nm): 800-1650Calibration wavelength: 850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nmDetector: InGaAsAccuracy: Resolution: Linearity: 0.1%, Non-linearity: 0.01dBm Working temperature: -10℃-+50℃Storage temperature: -20℃~+70℃ Relative humidity: 90% (+ 30°C)Connector: Removable for FC/PC SC/PC Power supply: 3xAAA batteries (delivered without batteries) Operating time: > 120 hours (without backlight)
