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)
7.1. Equipment
•
Electromagnatic radiation monitor
•
Glass thermometer 212°F or 100°C
•
600cc glass beaker
7.2. 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
.
1. Pour 275 ± 15cc (9ozs
s
± 1/2oz) of 20°C ± 5°C (68° ± 9°F)
water in a beaker which is graduated to 600cc, and place in
the center of the oven.
2. Set the radiation monitor to 2450MHz and use it following
the manufacturer´s recommended test procedure to assure
correct results.
3. When measuring the leakage, always use the 2 inch (5cm)
spacer supplied with the probe.
4. Tap the [Start] pad or set the timer and with the magnetron
oscillating, measure the leakage by holding the probe
perpendicular to the surface being measured.
7.2.1. Measurement with the outer panel
removed.
Whenever you replace the magnetron, measure for radiation
leakage before the outer panel is installed and after all
necessary components are replaced or adjusted. Special care
should be taken in measuring around the magnetron.
7.2.2. Measurements with a fully
assembled oven.
After all components, including outer panel are fully assembled,
measure for radiation leakage around the door periphery, the
door viewing window, the exhaust opening, control panel and
air inlet openings.
7.3. Record keeping and
notification after measurement
•
After any adjustment or repair to a microwave oven, a
leakage reading must be taken. Record this leakage
reading on the repair ticket even if it is zero.
A copy of this repair ticket and the microwave leakage
reading should be kept by repair facility.
•
Should the radiation leakage be more than 2 mW/cm
2
(1mW/cm
2
for Canada) after determining that all parts are in
good
condition,
functioning
properly,
and
genuine
replacement parts as listed in this manual have been used,
immediately notify PSTC, PPR or PCI.
