Check for radiation leakage after every servicing. Should
the leakage be more than 2 mW/cm

. After repairing

or replacing any radiation safety device, keep a written
record  f o r  fu tu re reference,  the leakage reading
must be recorded on the service repair ticket while in
the customer’s home.

Note before measuring.
(1) Do not exceed meter full scale deflection. Leakage monitor

should initially be set to the highest  scale.

(2) 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).

(3) Leakage with the outer panel removed ...... less than 5mW/cm

(4) Leakage for a fully assembled oven with door normally closed

...... less than 2mW/cm

beaker which is graduated to  600cc, and place in the center of the
oven.

(B) Set the radiation monitor to 2450MHz and use it following the

manufacturer’s recommended test procedure to assure correct
results.

(C) When measuring the leakage, always use the 2 inch (5cm) spacer

supplied with the probe.

(D) 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.

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 measur
ing around the magnetron.

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.

After any adjustment or repair to a microwave oven, a leakage read-
ing 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.

Avoid contacting any high voltage parts.
