Feature description

1. The voltmeter connection is simple. Two lines are routinely used, the red connection is positive, the black connection is negative, and the reverse connection protection is inside.

2, conventional external power supply is not needed, it can be measured directly by measuring voltage, and the voltage range is three lines 0-100V.

3, wide voltage operation, red minimum measurement voltage0V, maximum safety pressure can reach 100V, more than 100V may be damaged.

4. When measuring the voltage below 10V, the two digit is displayed after the decimal point. When measuring the voltage above 10V, a digit is displayed after the decimal point.
