Record Keeping And Notification After Measurement; Measurement With A Fully Assembled Oven - LG LMH1017CVW Service Manual

MEASUREMENT WITH OUTER CASE
REMOVED
• When you replace the magnetron, measure for
microwave energy leakage around the door view
window, the exhaust opening, and air inlet opening
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. (Circled area of Fig. below)
- Around the magnetron
- The waveguide
WARNING : AVOID CONTACTING ANY
HIGH VOLTAGE PARTS
MEASUREMENT WITH A FULLY
ASSEMBLED OVEN
• After all components, including the outer case, are fully
assembled, measure for microwave energy leakage
around the door viewing window.
NOTES WHEN MEASURING
• Do not exceed meter full scale deflection.
• The test probe must be removed no faster than
1 inch/sec (2.5 cm/sec) along the shaded area,
otherwise a false reading may result.
• 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.
• 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
• 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.
• The microwave energy leakage should not be more than
5 mW/cm 2 . after determining that all parts are in good
condition, functioning properly and genuine replacement
parts which are listed in this manual have been used.
• At least once a year, have the electromagnetic energy
leakage monitor checked for calibration by its
manufacturer.
