A » To test a transformer with a multimeter, first ensure the power is off. Set the multimeter to the resistance (ohm) setting, then check the primary winding by connecting the probes to the input terminals. Next, test the secondary winding by connecting the probes to the output terminals. A continuous circuit indicates healthy windings, while infinite resistance suggests a fault. Always follow safety precautions when handling electrical components.

A »To test a transformer with a multimeter, measure the resistance of the primary and secondary coils using the ohms function. Then, check for continuity between the coils and the transformer's casing. Finally, measure the voltage output using the AC voltage function to ensure it's within the transformer's rated output.
