E. A  microwave leakage check to verify

Compliance with the Federal performance 
Standard should be performed on each 
oven prior  to release to the owner.

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.
2. Stir water in glass vessel with thermometer, and record glass vessel’s temperature (“T1”, 10   1  C).

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;

Output =       4.187x1000x     T+0.55xMcx(T2-T0)

Additional power test should be made if temperature rise is marginal.
