How to Calibrate the Digital Tube Voltmeter
(Optional steps for the person who need a highly accurate voltage value)
1. Short press the left “ON/OFF” button to start up the digital tube voltmeter. Long press(>1s, <4 seconds)="" the="" left="" button="" to="" shut="" down="" the="" digital="" tube="" voltmeter.="">4>
2. Long press(>4 seconds) the left button to enter self-calibration of voltage measurement(calibration range: -0.5-0.5V, factory setting is 0.0).
“IN” indicator lights = input voltage measurement calibration starts.
Then, long press(>2 seconds) the right “Mode” button, “OUT” indicator lights = output voltage measurement calibration starts.
Tap the left / right button to reduce / rise by one unit (since the voltage value of one unit is less than 0.1V, you need to 1-5 times tap the button continuously, so that the voltmeter can change by 0.1V)
3. After calibration, long press(>2 seconds) the right “Mode” button to preserve the adjusted value(no loss with outage) and back to normal voltage display.
