The output power of the magnetron can be measured by performing a water temperature rise test. Equipment needed: * Two 1-liter cylindrical borosilicate glass vessel (Outside diameter 190 mm) * One glass thermometer with mercury column NOTE: Check line voltage under load. Low voltage will lower the magnetron output. Make all temperature and time tests with accurate equipment. 1. Fill the one liter glass vessel with water. _ 1 C). 2. Stir water in glass vessel with thermometer, and record glass vessel’s temperature (“T1”, 10+ 3. After moving the water into another glass vessel, place it in the center of the cooking tray. Set the oven to high power and operate for 47 seconds exactly. ( 3 seconds included as a holding time of magnetron oscillation) 4. When heating is finished, stir the water again with the thermometer and measure the temperature ( “T2”). 5. Subtract T1 from T2. This will give you the water temperature rise. ( T ) 6. The output power is obtained by the following formula; 45 : Heating Times (sec) Output = 4.187x1000x T+0.55xMcx(T2-T0) ( 3 seconds included as a holding time 42 of magnetron oscillation.) 4.187 : Coefficient for water 1000 : Water ( cc ) T : Temperature Rise (T2-T1) T0 : Room Temperature Mc : Cylindrical borosilicate glass weight 7. Normal temperature rise for this model is 9.9 C to 10.3 C at ‘HIGH’. NOTE 1: Variations or errors in the test procedure will cause a variance in the temperature rise. Additional power test should be made if temperature rise is marginal. NOTE 2: Output power in watts is computed by multiplying the temperature rise (step 5) by a factor of 91 times the of centigrade temperature. Capacitor 1. Remove wire leads. 2.
