2. Error adjustment
The product is calibrated 100% before delivery, the user can adjust error manually. the method is as follows
Step 1: long press the key (about 3 seconds) until the screen digit flashes, then release the key;
Step 2: Digital flicker means entering error adjustment state, and the digit cycle flickers in sequence: voltage high digit→voltage middle digit→voltage low digit→voltage decimal point→ampere high digit→ampere middle digit→ampere low digit→ampere decimal point. The flicker represents the present adjustable digit, short press the key to adjust the value (Digital 0-9 cycle, decimal point shift);
Step 3: long press the key (about 3 seconds) after the adjustment, the screen display PASS and return to the normal display interface, means the adjustment is successful.
Note: error adjustment must be carried out under pure resistance (PF=1.00) load environment, otherwise the active power error after adjustment will be too large!
