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
- Leakage for a fully assembled oven with door normally closed ......
less than 2mW/cm
- Leakage for a fully assembled oven [Before the latch switch
(primary) is interrupted] while pulling the door ...... less than 2mW/
cm .

1. Pour 275 ± 15cc (9ozs ± 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.
3.2.1. 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.
3.2.2. 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.
3.3. Record keeping and notification after measurement
1. 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.
