Reset button long press all data (mAh, Wh, 00:00:00) 2. Quick button twice to reset capacity (mAh) 3. Quickly press three Power Reset (Wh) 4. Quick button four for reset time (00:00:00) 5. Quick key five. Set up automatic standby and discharge countdown to remind regularly 6. If no load output no load, quick seven keys and for the current zero to zero in the current ambient temperature for accurate calibration, so can make more accurate measurement in small current. Package included: 1 x 150W USB Mobile Power Tester 1 x Charger 1 x Crocodile Clamp Cable 1 x Crocodile Clip to USB Male Head Annotation: 1.Exceeding the specified power will cause the product to burn. 2. When testing the high voltage battery and large power supply, the two power buttons must be adjusted counterclockwise to a minimum of zero before use. After connecting, the current regulator is slowly adjusted according to the display current power. The big tune is full, so there is a big risk that the load will burn out the discharge tube due to instant power supply. Please pay attention to this point when using.
