Volt-Ohm Meter
Definition and meaning of Volt-Ohm Meter in real estate.
A volt-ohm meter, also known as a multimeter, is a handheld testing device used to measure electrical voltage, current, and resistance across circuits.
In more detail
The device features a digital or analog display connected to two insulated testing probes that are placed against electrical contacts. By measuring voltage, the tool confirms whether an outlet has power and is wired correctly to the standard household voltage. Checking ohms, which measures resistance, helps determine if a circuit has a complete path, called continuity, or if a wire is broken.
Using a volt-ohm meter is a standard safety precaution to ensure electrical systems do not pose a fire or shock hazard to occupants.
