1. MEASUREMENT OF THE MICROWAVE POWER OUTPUT
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 microwave oven supplied at rated voltage and operated at it is
maximum microwave power setting with a load of 1000
±
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 190mm.
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
℃
(50
±
3.6
℉
). 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 A seconds. (Refer to table as
following) Heating time is measured while the microwave generator
is operating at full power. The filament heat-up time for magnetron is
not included.
6. The initial and final temperature of water is selected so that the
maximum difference between the ambient and final water
temperature is 5K.
7. The microwave power output P in watts is calculated from the
following formula:
P = 4187
× △
T/ t
·△
T is difference between initial and ending temperature.
·
t is the heating time.
The power measured should be B (Refer to SPECIFICATIONS) W
±
10.0 %.
CAUTION
1. Water load should be measured exactly to 1 liters.
2. Input power voltage should be exactly specified voltage (Refer to SPECIFICATIONS).
3. Ambient temperature should be 20

)
