MICROWAVE AND LEAKAGE TESTS
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 and necessary.
Prepare a glass beaker with a diameter of approx. 190 mm round. with a max. 3 mm wall thickness.
Fill the beaker with exact 1 liter of cold water with an temperature of 10-12 ˚C measure the temperature
of the water before placing into the oven.
Start the oven for 1 min. on full power (only microwave) check the time by your writwatch after the
magnetron takes full power (Ampere meter).
The unit should be heated up 2-3 times before the test starts.
Check the water temperature under stirring the water and calculate the difference to the start temperature.
˚C x 70(multiplicator)=watt
Please take under consideration that always the measured power output is 15-20% lower than the rating plate
shows. 850 W = 720-680 W if the measured output is below this rate please repeat the measurement.
