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.
12.2.1. 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.
WARNING
Avoid contacting any high voltage parts.
12.2.2. 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 and air inlet openings.
12.3. 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 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 PASC, PSC or PCI.
12.4. At least once a year, have the radiation monitor checked for
calibration by its manufacturer.
