A mini 2-wire voltmetermeasures a DC (Direct Current) voltageranging from 2.5 to 40V DCand has a0.28 inch LED display. The 2-wire configuration has a red and black wires. It is a commonly used configuration for measuring electrical potential difference across two points in a circuit using only two connection wires.
The 2-wire setup is easy to install and use, often ideal for quick voltage checks in the field.
