31++ How to test a relay with a multimeter sample

How To Test A Relay With A Multimeter. A relay is defined as an electrically controlled device that opens and closes electrical contacts with help of electromagnetic switching, and performs on and off operation of other devices in the electrical circuit. After you access the relay and compressor on your fridge, use a multimeter to test the ports to make sure it has a low resistance. If the multimeter does not beep, the coil is open & damaged.the relay needs to be replaced.; The multimeter is placed in the “r×100” or “r×1k” gear, and the two test leads (regardless of positive and negative) are connected to the two pins of the relay coil (shown in figure 5).

A strong click from the starter relay shows its working while a series of weak click or a single weak click show its bad and needs replacement. An important relay in your car is the ignition relay. When a relay is not working, then the meter will read zero or ol. To test continuity, all you have to do is stick 2 terminals on your multimeter against 2 ends of an electrical current. If the multimeter has multiple ranges within the ohm setting, choose the lowest range possible to get the most accurate reading. Some of the benefits are that they are simple to use and cheaper.

You can buy a multimeter from your local hardware store.

Set the multimeter to 20v dc; Do the test with a multimeter electromechanical relay em. Kita dapat menggunakan multimeter analog maupun multimeter digital untuk mengukur atau menguji apakan relay yang ingin kita uji tersebut dalam kondisi baik ataupun tidak. In this article, we will show what resistance readings you should get when you measure various points of a relay. The relay can be destroyed over time, which can cause your car to stall during operation. To test continuity, all you have to do is stick 2 terminals on your multimeter against 2 ends of an electrical current.
