NOTE :
Some inexpensive meters
may indicate infinite
resistance in both direction.
Measure the resistance.
(Ohm-meter scale: Rx1000)
• Terminal to terminal.
Measure the resistance.
(Ohm-meter scale: Rx1000)
• Terminal to case.
Measure the continuity (Forward).
(Ohm-meter scale: Rx10000)
Measure the continuity (Reverse).
(Ohm-meter scale: Rx10000)
Normal: Momentarily indicates
several ohms, and
then gradually returns
to infinite.
Normal: Infinite.
Normal: Continuity.
Abnormal: Infinite.
Normal: Infinite.
Abnormal: Continuity.
NOTE: When testing the magnetron, be sure to install the magnetron gasket in the
correct position and be sure that the gasket is in good condition.
