5. MICROWAVE AND 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 C, then the microwave
generating system is working.
