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.
PR O CED U R E
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 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 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 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:
T
is difference between initial and ending temperature.
t is the heating time.
The power measured should be B (Refer to 2. SPECIFICATIONS) W ± 10.0 %.
Heating time for power output:
A (second) 70 64 60 56 52 49 47 44 42 40 38
B (W ) 600 650 700 750 800 850 900 950 1000 1050 1100

1. W ater load should be m easured exactly to 1 liters.
2. Input pow er voltage should be exactly specified voltage (Refer to 2. S P E CIF IC AT IO N S ).
3. A m bient tem perature should be 20 ± 2° C (68 ± 3.6° F )
