Check Doorbell Chime

What happens here

After confirming the transformer's output, the electrician checks the existing doorbell chime, which is a traditional mechanical chime unit. He also uses the multimeter to test the connections at the chime. The chime appears to be in good working condition, further narrowing down the potential sources of the problem. This indicates that the power pathway from the transformer to the chime is likely intact.

Goal: Verify the functionality of the existing doorbell chime.
