Always remove the leads in reverse order after testing: red first, then black.To use a multimeter to check the voltage of your doorbell transformer: Disconnect your existing doorbell. Note: Make sure that the wires from the doorbell don’t fall inside the wall. Set the knob on your multimeter to AC (the V with a wavy line on top or next to it). Connect the two probes from the multimeter to the wires from your doorbell.Test continuity in the transformer. To test a step-down transformer with a multimeter, adjust your multimeter to resistance ( ohm) at a higher range ( above 2k) for the primary coil. After setting your multimeter, connect both probes to the primary coil terminals. The prime coil is expected to have around 1000 ohms (1k).Jul 18, 2023 · Step 4: Measure the voltage at the secondary side. Measuring the output voltage of the transformer. Set the multimeter knob to 200 V AC. While the transformer is powered on, test the voltage at the secondary winding. The measured voltage should be close to the rated step-down voltage of the transformer. Step 4. Test the transformer's output voltage with the multimeter. Compare the reading to the stated output voltage. If the output voltage has a correct reading, the transformer works properly. If the input voltage has a correct reading, but the output voltage has a high or low reading, the secondary windings have a fault.How to test an NPN transistor using a multimeter. Base and emitter: Touch the red probe to the base terminal and the black probe to the emitter terminal. For an NPN transistor, this is the forward bias configuration of the base-to-emitter PN junction. So, the ideal voltage should be between 0.4 to 0.9 volts.Your multimeter is set to measure ac voltage in the range of 0-200V as pictured which is fine (your doorbell transformer is probably AC). First measure voltage at the doorbell. If you get ~16V the problem is with your doorbell. If not you need to determine the root cause.Aug 27, 2023.
