COMPONENTS HIGH VOLTAGE CAPACITOR TEST PROCEDURE Chassis Antenna Gasket Filament RESULTS 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. Measure the resistance. (Ohm-meter scale: Rx1000) ¥ Terminal to terminal. Normal: Momentarily indicates several ohms, and then gradually returns to infinite. Measure the resistance. (Ohm-meter scale: Rx1000) ¥ Terminal to case. Normal: Infinite. HIGH VOLTAGE DIODE Measure the continuity (Forward). (Ohm-meter scale: Rx10000) Normal: Continuity. Abnormal: Infinite. NOTE : Some inexpensive meters may indicate infinite resistance in both direction. Measure the continuity (Reverse). (Ohm-meter scale: Rx10000) Normal: Infinite. Abnormal: Continuity. 5-9
