The self-calibration method of voltmeter:
1. When the voltmeter shows output voltage, long press the right button
for 2 seconds, then release, voltmeter and "OUT" LED flash in
synchronization. Now the voltmeter enters into output voltage
calibration mode. Similarly, when the voltmeter shows input voltage,
long press the right button for 2 seconds, then release, voltmeter and
"IN" LED flash in synchronization, now the voltmeter enters into input
voltage calibration mode.
2. Touch the right button, the voltage
rises a unit; Touch the left button, the voltage drops a unit. Due to a
unit is less than 0.1 V, so you need to continuously press 5 times to
see that the voltmeter changes 0.1 V.
3. After calibration, long
press the right button for 2 seconds, then release. Now the voltmeter
exits the voltage calibration mode. All the parameters will be saved
automatically.
Note: Once calibrate the voltmeter, you can get the accurate voltage value on the whole voltage range.
