2.2. Measurement of microwave output
The output power of the magnetron can be determined by performing IEC standard test procedures. However,due to the complexity of IEC test procedures, it is recommended to test the magnetron using the simple method outlined below. Necessary Equipment: *1 liter beaker *Glass thermometer / *Wrist watch or stopwatch NOTE:

Check the line voltage under load.Low voltage will lower the magnetron output. Take the temperature readings and heating time as accurately as possible. 1. Fill the beaker with exactly one liter of tap water.Stir the water using the thermometer and record the water�s temperature. (recorded as T1). 2. Place the beaker on the center of glass tray. / Set the oven for High power and heat it for exactly one minute. 3. Stir the water again and read the temperature of the water. (recorded as T2). 4. The normal temperature rise at High power level for each model is as shown in table.
