2. MICROWAVE RADIATION 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 275mL(9. oz.) glass of water in the center of the oven bottom.
3. Select “HIGH” cook power, turn the microwave oven on, and test for R.F leakage using the following pattern:
a) Check around the cabinet at the front
b) Check around the door
c) Check around the console panel
d) Check horizontally across the door
e) Check vertically across the door
f) Check diagonally across the door
g) Check across the air vents
h) Check across the rear air vent
EQUIPMENT
• Electromagnetic energy leakage monitor(NARDA 8100B,HOLADAYH1501).
* 600 cc glass beaker with an inside diameter of approx. 8.5cm (3.5in).
* Glass thermometer 100˚C or 212˚F
When checking for R.F leakage, use an approved R.F measuring device to assure less than 4mW/cm
2
emission at
5cm distance with a maximum scan rate of 2.5cm/second, in compliance with U.S. Government Department of
Health, Education and Welfare 21 CFR1030, performance Standard for Microwave Ovens.
A proper operating door and seal assembly will normally register small emission, but they must be no greater than
4mW/cm
2
to allow for measurement uncertainty.
All microwave ovens exceeding the emission level of 4mW/cm
2
must be reported to Department of Service for
microwave ovens immediately and the owner should be told not to use the microwave oven until it has been repaired
completely.
WARNING :
The scan speed is 1 in./sec.
