10.2. Measurement of microwave output
The power output 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 (Celsius scale) *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 beaker's temperature (recorded as T1) 2. Place the beaker on the center of ceramic shelf. 3. Set the one to High power and heat it for exactly one minute. 4. Stir the water again and read the temperature of the beaker (recorded as T2). The normal temperature rise (T2-T1) at High power output for each model is as shown in table.
