MEASUREMENT AND TEST
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 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 tim e should be exactly A seconds (Refer to table as follow ing).
Heating tim e is m easured while the m icrowave generator is operating
at full power. The filam ent heat-up tim e for m agnetron is not included.
6. T he initial and final tem perature of w ater is selected so that the m axi-
m um difference between the am bient and final water tem perature is 5K .
7. The m icrowave power output P in watts is calculated from the following
form ula:
•
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 2. SPECIFICATIONS).
3. Ambient temperature should be 20 ± 2°C (68 ± 3.6°F)
