Calibration : Apply USB power and simultaneously press all three buttons to enter the calibration mode and perform the following steps
The first calibration step after entering the calibration displays the 0u0A; short connect both positive and negative input terminal and press the "OK" button
Next, the display will show J10u; apply 10.00V DC between the input positive and negative terminal and press the "OK" button again.
The display will show J2.0A; apply 2.0 A DC current between the input terminals and press the "OK" button to complete the calibration.
If the tester determines that the calibration data is reliable, it will in turn show 4 calibration numbers after completing the procedure; otherwise it will ignore the calibration attempt, discard the data and exit the procedure.
