WebVoltmeters are used to measure the voltage that exists in a circuit. Typically, the technician selects an appropriate scale (0-150 volts, 0-250 volts, 0-500 volts, etc.), and then clamps one of the probes to one of the hot lines. The other probe is then carefully put in contact with the other hot line, and the meter registers the voltage.
