How do you use an ohmmeter
WebApr 25, 2024 · Set your multimeter to ohms mode. Then, measure the resistance by touching the leads across the coil pins. A standard coil is anywhere between 40Ω to 120Ω. A poor electromagnet coil winding suggests the relay is out of range or open, and it’s time to replace it. Then, keep the multimeter in ohms or continuity mode. WebAn ohmmeter applies current to the circuit or component whose resistance is to be measured. It then measures the resulting voltage and calculates the resistance using Ohm’s law =. An ohmmeter should not be connected …
