- Small size (48x29x21mm), easy to carry out and install.
- High precision: the measurement range of 0-33.000V over the traditional 0-20.000V header.
- With reverse connection protection to avoid burning out.
- Red wire: Power Supply+; Yellow wire: Measure Voltage+; Black wire: Power Supply-, Measure Voltage-.
- NOTE: The voltmeter needs isolated power supply and the range of power supply is DC 3.5-30V.

The voltmeter needs isolated power supply. Power supply range is DC 3.5-30 V.
when black wire and red wire are switched to with the power supply, the voltmeter will display 0.000 (when the measuring line is dangling ,the voltmeter will display one or two base).
Yellow wire and black wire will be switched to the measurement circuit. The measured voltage range is DC 0-33.000 V.
Red: Power Supply +(DC 5-30V)
Black: Power Supply -, Measure –
Green: Measure +
