Measurement With The Outer Case Removed; Measurement With A Fully Assembled Oven; Record Keeping And Notification After Measurement - GE JVM1790CK01 Service Manual

MEASUREMENT WITH THE OUTER CASE
REMOVED
(1) When you replace the magnetron, measure for
microwave energy leakage before the outer case
is installed and after all necessary components
are replaced or adjusted. Special care should be
taken in measuring the following parts.
- Around the magnetron
- The waveguide
WARNING: AVOID CONTACTING ANY HIGH
VOLTAGE PARTS.
MEASUREMENT WITH A FULLY
ASSEMBLED OVEN
(1) After all components, including the outer
panels, are fully assembled, measure for
microwave energy leakage around the door
viewing window, the exhaust opening and air
inlet openings.
(2) Microwave energy leakage must not exceed the
values prescribed below.
NOTES:
Leakage with the outer panels removed - less
than 5 mW/cm 2 .
Leakage for a fully assembled oven ("Before the
latch switch (primary) is interrupted") with the door
in a slightly opened position - less than 2 mW/cm
NOTE WHEN MEASURING
(1) Do not exceed meter full scale deflection.
(2) The test probe must be removed no faster than
1 inch/sec (2.5cm/sec) along the shaded area,
otherwise a false reading may result.
(3) The test probe must be held with the grip portion
of the handle. A false reading may result if the
operator's hand is between the handle and the
probe.
(4) When testing near a corner of the door, keep
the probe perpendicular to the surface making
sure the probe horizontally along the oven
surface, this may possibly cause probe damage.
RECORD KEEPING AND NOTIFICATION
AFTER MEASUREMENT
(1) After adjustment and repair of any microwave
energy interruption or microwave energy blocking
device, record the measured values for future
reference. Also enter the information on the
service invoice.
(2) Should the microwave energy leakage not be
more than 2 mW/cm
parts are in good condition, functioning properly
and genuine replacement parts which are listed in
this manual have been used.
(3) At least once a year, have the electromagnetic
2 .
energy leakage monitor checked for calibration
by its manufacturer.
