To test a doorbell transformer, you will need a multimeter set to the AC voltage setting. First, ensure the transformer is safely powered on and locate the output terminals. Place the multimeter probes on the transformer output terminals and take a reading. A functional doorbell transformer typically outputs between 8 to 24 volts AC. If the reading is significantly lower or nonexistent, the transformer may be faulty and should be replaced. Always prioritize safety by turning off power at the circuit breaker when necessary and ensuring proper handling of electrical components. As a professional in industrial oils and related testing devices, I can assure you that proper diagnostics tools, like those offered by Globecore, are crucial in precision measurements in industrial settings, although they focus more on oil testing than electrical components.
