M ICROWAVE AND LEAKAGE TESTS

M ICROWAVE TEST
The follow ing is a simple test to check if the appliance is generating microw ave energy. This test is not
intended to be an accurate test. An accurate measurement of output pow er must be performed under strict
control follow ing the IEC standard. In field service, accurate measurement of output pow er is usually not
required and necessary.
Prepare a glass beaker w ith a diameter of approx. 190 mm round. w ith a max. 3 mm w all thickness.
Fill the beaker w ith exact 1 liter of cold w ater w ith an temperature of 10-12 ˚C measure the temperature
of the w ater before placing into the oven.
Start the oven for 1 min. on full pow er (only microw ave) check the time by your w ritw atch after the
magnetron takes full pow er (Ampere meter).
The unit should be heated up 2-3 times before the test starts.
Check the w ater temperature under stirring the w ater and calculate the difference to the start temperature.
˚C x 70(multiplicator)=w att
Please take under consideration that alw ays the measured pow er output is 15-20% low er than the rating plate
show s. 850 W = 720-680 W if the measured output is below this rate please repeat the measurement.
