MICROWAVE AND MICROWAVE LEAKAGE TESTS
5.1
MICROWAVE TEST
The following is a simple test to check if the appliance is generating microwave
energy. This test is not intended to be an accurate test. An accurate measurement
of output power must be performed under strict control following the IEC standard.
In field service, accurate measurement of output power is usually not required.
1.
Prepare a beaker of water of quantity about 1000cc.
2.
Measure the temperature of the water before putting into the oven.
3.
Heat the water in the oven with full power (microwave only) for 60 seconds.
4.
Again measure the temperature of the water.
5.
If the temperature rise by about 10 degree Centigrade, then the microwave
generating system is working.

MICROWAVE LEAKAGE TEST
5.2.1 TESTING EQUIPMENT
600cc beaker
Microwave meter
5.2.2 TESTING PROCEDURE
1.
Place 275cc of water into the beaker and place it in the center of the oven.
2.
