How to test a relay with a multimeter is good or bad

How to test a relay with a multimeter is good or bad

Answer:

With the ohm file test coil, there are numerical or pointer bias, indicating that the coil is good Or ohm file test, only measured normally closed, there are numerical or pointer bias, indicating that normally closed is good, Measured normally open, must be in the coil 2-side voltage, the relay closed, and then measured normally open, there are numerical or pointer bias, indicating that normally closed is good

Can only be judged, such as the coil should have a certain resistance, normally closed contact resistance is zero. Normally open contact resistance infinity.
