The Meter, also known as Ohm-Meters and Volt-Meters are testing tools used in the security trades to ensure systems are correctly wired with the right Voltage, Amperage and Polarity.
Meters also measure Continuity and Resistance. Most meters can provide an audible tone when continuity is present.
Confused?? Let’s define the terms: Voltage, Polarity, Amperage, Continuity and Resistance. We’ll also show you where to set your meter to get the proper reading for each measurement.
