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. Package included 1 x PZEM-026 AC Voltmeter Ammeter
