3. POWER OUTPUT MEASUREMENT
(1) Prepare 1000t5g tap water.
(2) Adjust water temperature to 10°f20C.
(3) Pour water into acontainer made of borosilicate
glass, 190mm outer diameter cylinder, maximum
3mm thickness.
Note: Use the container kept on the room tempe-
rature.
‘4) Place the container in the center of overr cavity.
‘%5) Set the heating time for 60 seconds and rating full
power and then start 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 shall be 8° to 12°C.

The
Before the power is applied:
Open and close door serveral times to make sure the
primary interlock switch, the interlock monitor
switch and the door sensing switch operate proper-
ly. (Listen for the clicking sound from the switches.)
Make sure the interlock monitor switch closes after
the primary interlock switch is opens when the door
is opened.
(See pages 1and 6)
Make sure the perforated screen and the choke di-
electric of the door are correctly mounted.
After the power is applied:
Open arid close the door to see if the interlock
mechanism operates properly.
Check microwave energy leakage with aleakage
detector and confirm the energy leakage is below 5
mWfcm2.
Do not operate the unit until it is completely re-
paired, if any of the following conditions exists.
Door does not close firmly against the cavity front.
The hinge is broken.
The choke dielectric or the door seal is damaged.
The door is bent or warped, or there is any other
visible damage to the oven that may cause micro-
wave energy leakage.
NOTE: Always keep the seal clean.
Make sure that there are no defective parts in the
interlock mechanism.
Make sure that there are no defective parts in the
microwave generating and transmission assembly.
[especially waveguidej
The following items should be checked after the
unit is repaired:
The interlock monitor switch is connected correctly
and firmly.
The magnetron gasket on the magnetron is properly
positioned.
Waveguide and oven cavity are intact (no leakage of
microwave energy).
The door can be properly closed and the safety
;witches work properly,
I_he oven must be stopped when the door is opened
>r the time is up.
oven must not be operated with any of the above
components removed or bypassed.
