A » To test a relay in a control panel, first, ensure power is off and identify the relay's coil and contacts. Use a multimeter to check coil resistance—typically between 50-500 ohms. Then, apply the correct voltage to the coil and verify the contact operation using the multimeter's continuity setting. If the relay clicks and continuity is confirmed, it functions correctly; otherwise, consider replacement.

A »To test a relay in a control panel, first, ensure the panel is de-energized. Then, use a multimeter to check continuity between the relay's coil terminals and verify the relay's operation by applying voltage to the coil and checking the switching contacts.
