Instructions for Use:

1.The voltmeter can be turned off.Press and hold the switch for 4 seconds,and then it can be turned off by letting go.

2.Input and output voltage measurement error calibration function,long press the switch for more than 4 seconds,after letting go,it will enter the voltage measurement error calibration function.

3.The digital tube flashes to display the voltage calibration ratio value (range -5V~5V).At this time,short press the button to change this value (cycle between -5V~5V).

4.When the voltage value displayed by the voltmeter is too high,lower the reference value (adjust to a negative number).

5.When the voltage value displayed by the voltmeter is low,increase the reference value (adjust to a positive number).

6.After adjusting to the reference value you want,press and hold the button for more than 2 seconds. After letting go,save the set value and return to the normal display voltage.The set correction value will take effect immediately and will not be lost after power failure.
