When troubleshooting power and control circuits, approximate meter readings should be anticipated if the meter readings are going to be used to help determine circuit problems. Determine the expected DMM reading if the ciircuit is working properly. The expected reading of DMM 1 with the motor on is what VAC? And the expected reading of DMM 2 with the motor is on is what VAC? And The expected reading of DMM 3 with the motor on is What mA?
