3. POWER OUTPUT MEASUREMENT
(1) Prepare 1000±5g tap water.
(2) Adjust water temperature to 10 o C±2 o C.
(3) Pour water into a container made of
borosilicate glass, 190mm outer diameter
cylinder, maximum 3mm thickness.
(4) Place the container in the centre of the oven
cavity.
(5) Set the heating time for 47 seconds at full
power and start the oven.
(6) Take the container out immediately when
heating time is up.
(7) Stir water for making even water temperature
in the container.
(8) Measure water temperature.
Water temperature rise should be between 8˚C to 12˚C
for correct power output.

FOLLOWING PRECAUTIONS MUST BE
(After 15mins.)
TAKEN BEFORE SERVICING.
Magnetron, Open
(1)Before the power is applied.
(a)Open and close door several times to make sure

(2)After the power is applied.
(a)Open and close the door to see if the interlock

mechanism operates properly.
(b)Check microwave energy leakage with a leakage
detector and confirm the energy leakage is below
5mW/cm
(3)Do not operate the unit until it is completely
repaired, if any of the following conditions exists.
(a)Door does not close firmly against the cavity front.
(b)The hinge is broken.
(c)The choke dielectric or the door seal is damaged.
(d)The door is bent or warped, or there is any other
visible damage to the oven that may cause
microwave energy leakage.
NOTE: Always keep the seal clean
(e)Make sure there are no defective parts in the
microwave generating and transmission assembly.
(especially waveguide).
(f)Make sure there are no defective parts in the inter
lock mechanism.
(4)Following items should be checked after the unit is
repaired.
(a)The interlock monitor switch is connected
correctly and firmly.
(b)The magnetron gasket on the magnetron is
properly positioned.
(c)Wave guide and oven cavity are intact ( no leakage
of microwave energy).
(d)The door can be properly closed and the safety
switches work properly.
(e)The oven must be stopped when the door is
opened or the time is up.
The oven must not be operated with any of the above
components removed or bypassed.
