R.F. LEAKAGE TEST

CAUTION

EQUIPMENT

•Electromagnetic energy leakage monitor (NARDA 8100B, HOLADAY H1501).

•600 ml glass beaker.

•Glass thermometer 100°C or 212°F.

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 mi- crowave oven on, and test for R.F. Ieakage at the following locations using the pat- tern 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 than 4 mw/cm2 emission at 5 cm distance with a maximum scan rate of 2.5 cm/second, in 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/cm2 to allow for 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/cm2 must be reported to Dept. of 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.

*CDRH: Center for Device and Radiological Health, Food and Drug Administration.

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—primary and secondary interlock switches and the monitor switch with new ones because the contacts of those interlock switches may be melted and welded together.

All repairs must be performed in such a man- ner that microwave energy emissions are mini- mal.

Address for CDRH is:
