3. PROCEDURE FOR MEASURING MICROWAVE
ENERGY LEAKAGE
WARNING
Check for radiation leakage after every servicing.
Should the leakage be more than 2 mW/cm
2
(1mW/
cm
2
for Canada) inform PASC, PSC, or PCI
immediately. After repairing or replacing any
radiation safety device, keep a written record for
future reference, as required by D.H.H.S. and Health
and Welfare Canada regulation. This requirement
must be strictly observed. In addition, the leakage
reading must be recorded on the service repair
ticket while in the customer’s home.
NOTE:
The U.S. Government standard is 5 mW/cm
2
while in the customer’s
home. 2mW/cm
2
stated here is our own voluntary standard. (1mW/
cm
2
for Canada)
3.1. Equipment
- Electromagnatic radiation monitor
- Glass thermometer 212°F or 100°C
- 600cc glass beaker
3.2. Procedure for measuring radiation leakage
Note before measuring.
- Do not exceed meter full scale deflection. Leakage monitor should
initially be set to the highest scale.
- To prevent false readings the test probe should be held by the grip
portion of the handle only and moved along the shaded area in
Figure no faster than 1 inch/sec (2.5cm/sec).
- Leakage with the outer panel removed ...... less than 5mW/cm
2
.
- Leakage for a fully assembled oven with door normally closed ......
less than 2mW/cm
2
(1mW/cm
2
for Canada).
- Leakage for a fully assembled oven [Before the latch switch
(primary) is interrupted] while pulling the door ...... less than 2mW/
cm
2
.
