Column (1) - Component Circuit.
Identifies circuit to be tested.
Column (2) - Heater Mode. Describes condition of heater for testing named circuit.
Column (3) - Test For/Meter Setting.
Describes proper setting of volt ohmmeter.
Columns (4 and 5) - Probe No. 1 and probe No. 2. Explains where each probe is
Probe numbers are arbitrary. Either probe may be placed at either position.
Column (6) - Meter Indication. What meter will show if circuit is good. Failure to achieve
indication means circuit is faulty.
