Digital USB Tester Voltage Current Power Meter for Phone Charging (White)

Directions for use: 1: Click the button to view 1-9 sets of charging data. 2: Long press the button for 3 seconds to remove a set of charging data. 3: Double-click the button to rotate the screen to view. 4. Long press the button and insert the USB interface to enter the voltage calibration: For example: (1) If display (5.526V→) Then double click button quickly (2) If display(5.528V↑), then you can click the button to increase the display voltage. (3) Double click button quickly, if display(5.528V↓),then you can click the button to decrease the display voltage. (4) Then double click button quickly again, if display(5.526V→),then click the button one more times, the screen will display Current Calibration! The system automatically performs current calibration and will automatically return to the function home page after calibration is completed.
