How Do You Test An AC Relay With An Analog Multimeter?
AC (alternating current) relays are used as remote switching devices. Relays typically employ two separate, but mechanically connected, parts for the operation. A solenoid coil magnetically activates a set or pair of electrical contacts. A single set of contacts is also referred to as a pole. Various AC relays may have many poles or sets of contacts. An analog test meter uses a display with a needle indicator on the face. Digital meters have now replaced analog meters, but analog devices are still highly accurate. Remove all electrical power to the AC relay device. This may entail pulling a control voltage fuse or switching off a circuit breaker that powers the relay control circuit. In some cases, there may be two separate power feeds for the relay. The control power that feeds the solenoid coil may be separate from the power feeding the relay contacts. Consult any electrical schematics to ensure all power is disabled. Use the screwdriver and remove one of the two wires that are conne
