MEASUREMENT OF THE MICROWAVE OUTPUT POWER

Microwave output power can be checked by indirectly measuring the temperature rise of a certain amount of water exposed to the microwave as directed below.

PROCEDURE

1.Microwave power output measurement is made with the microwave oven supplied at rated voltage and operated at its maximum microwave power setting with a load of 1,000¡ 5cc of potable water.

2.The water is contained in a cylindrical borosilicate glass vessel having a maximum material thickness of 3 mm and an outside diameter of approximately 190 mm.

3.The oven and the empty vessel are at ambient temperature prior to the start of the test. The initial temperature of the water is 10¡ 2˚C (50 ¡ 3.6˚F).

It is measured immediately before the water is added to the vessel. After addition of the water to the vessel, the load is immediately placed on the center of the shelf which is in the lowest normal position.

4.Microwave power is switched on.

5.Heating time should be exactly 49 seconds.

Heating time is measured while the microwave genera- tor is operating at full power.

The filament heat-up time for magnetrons is not included.

6.The initial and final water temperatures are selected so that the maximum difference between the ambient and final water temperatures is 5K.

Water Load

Tray

7. The microwave power output P in watts is calculated from the following formula:

P = 4187 X ΔT/t

•ΔT is actual temperature rise.

•t is the heating time.

The power measured should be 600W¡ 10.0%.

CAUTION :

1. Water load should be measured exactly to 1 liters.

2Input power voltage should be exactly 230V as specified.

3.Ambient temperature should be 20¡ 2˚C(68 ¡ 3.6˚F)
