Adjustment: The product is 100% calibrated before leaving the factory, and the user can also manually adjust the error by himself. The method is as follows: Step 1: Long press the button (about 3 seconds) until the digital digit on the screen flashes, then release the button; Step 2: Digital flashing means entering the error adjustment state, the digits flashing cyclically, followed by: high voltage>Voltage middle position>voltage low position>voltage decimal point>current high position>current middle position>current low position>current decimal point. Flashing represents the current adjustable digit. Short press the button to adjust the value (digit 0-9 cycle, decimal point shift); Step 3: After the adjustment is completed, press and hold the button (about 3 seconds), the screen displays PASS and returns to the normal display interface, indicating that the adjustment is successful.
