Connect the bell set or resistancemeasuring instrument across the relay terminals. Depress and release the reset arm to ensure the relay is reset. In this condition there should be continuity between the terminals. In the tripped condition, the circuit between the terminals should be open indicating the contacts are operating CR453AB, AC, AD normally. Remove the bell set or resistance measuring apparatus, rewire the relay terminals and reset the relay for normal operation.
