(D) When the heating is finished, again stir the water
with the thermometer and measure the temperature
rise as T2.
(E) Subtract T1 from T2. This will give you the water
temperature rise.
(F) The normal temperature rise for this model is 9°C
to 11°C (48°F to 52°F) at the "HIGH" power setting.
NOTE 1: Variations or errors in the test procedure will
cause a deviation in the temperature rise.
Additional
power test should be made if
@ One glass thermometer.
NOTE: Check the line voltage under load. Low voltage
will lower the magnetron output.
Make all
temperature and time tests with accurate equip-
NOTE 2: Output power in watts is computed by mul-
tiplying the temperature rise(step E) by a
power factor of 80.5 in the case of centigrade
temperature.
