1) Remove the outer case.
2) Disconnect two terminals, and remove one screw of

the earth terminal.

MEASUREMENT OF MICROWAVE POWER OUTPUT

• 

Microwave power output measurement is made with

the microwave oven supplied at its rated voltage and
operated at its maximum microwave power setting with
a load of (1000±5) g of potable water.

• 

The water is contained in a cylindrical borosilicate glass

vessel having a maximum material thickness of 3 mm
and an outside diameter of approximately 190mm.

• 

The oven and the empty vessel are at ambient

temperature prior to the start of the test.

• 

The initial temperature (T1) of the water is (10±2)°C. 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
turntable which is in thd lowest position and the
microwave power switched on.

• 

The time T for the temperature of the water to rise by a

value ∆ T of (10±2)°K is measured, where T is the time
in seconds and ∆T is the temperature rise. The initial
and final water temperatures are selected so that the
maximum difference between the final water
temperature and the ambient temperature is 5°K.

is measured while the microwave generator is

operating at full power. Magnetron filament heat-up
time is not included. (about 3 sec)

• 

The water is stirred to equalize temperature throughout

the vessel, prior to measuring the final water
temperature.

• 

Stirring devices and measuring instruments are

selected in order to minimize addition or removal of
heat.
