EQUIPMENT
• Electromagnetic energy leakage monitor
(NARDA 81 00B, HOLADAY H 1 501 ).
• 250 ml glass beaker.
TEST
On every service call, checks for microwave
energy emission must be made according to
the following manner.
1. Remove the cooking rack from the oven
cavity, if the microwave oven is so
equipped.
2. Place a 250 ML (8.0 oz.) glass of water in
the center of the oven bottom.
3. Select "HIGH" cook power, turn the micro-
wave oven on, and test for R.F. Ieakage at
the following locations using the pattern
shown below:
a) Around the cabinet at the front.
b) Around the door.
c) Across the console panel.
d) Horizontally across the door.
e) Vertically across the door.
f) Diagonally across the door.
g) Across the air vents.
h) Across the rear air vent.
i) All lockseams.
j) Weld at bottom.
k) Bottom plate.
I) Oven feet.
4. The scan speed is one inch per second.
When checking for R.F. Ieakage, use an ap-
proved R.F. measuring device to assure less
2
than 4 mw/cm emission at 5 cm distance with
a maximum scan rate of 2.5 cm/second, in
R.F. LEAKAGE TEST
compliance with U.S. Government Department
of Health, Education and Welfare 21 CFR1030,
performance Standard for Microwave Ovens.
A properly operating door and seal assembly
will normally register small emissions, but they
must be no greater than 4 mw/cm
measurement uncertainty.
NOTE: Enter leakage readings in space BE-
FORE and AFTER on the service document.
All microwave ovens exceeding the emission
level of 4 mw/cm
Service for microwave ovens immediately and
the owner should be told not to use the micro-
wave oven until it has been repaired com-
pletely.
If a microwave oven is found to operate with the
door open, report to Dept. of Service, the
manufacturer and CDRH* immediately. Also
tell the owner not to use the oven.
The interlock monitor switch acts as the final
safety switch protecting the customer from
microwave radiation. If the interlock monitor
switch operated to blow the fuse when the
interlocks failed, you must replace all interlock
switches with new ones, because the contacts
of those interlock switches may be melted and
welded together.
All repairs must be performed in such a manner
that microwave energy emissions are minimal.
