MEASUREMENT WITH THE OUTER CASE REMOVED
q
NOTES WHEN MEASURING
q q
Do not exceed meter full scale deflection.
When you replace the magnetron, measure microwave energy leakage before the out case is installed and after all necessary components are replaced or adjusted. Special care should be taken in measuring the following parts. (Shaded area of below Fig.) � Around the magnetron � The waveguide
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 q the handle. A false reading may result if the operator�s hand is between the handle and the probe.
q
WARNING: AVOID CONTACTING ANY HIGH VOLTAGE PARTS
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
q
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. Should the microwave energy leakage not be more than 4 mW/cm2 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 manufacture.

q
MEASUREMENT WITH A FULLY ASSEMBLED OVEN
q
After all components, including the outer case, are fully assembled, measure for microwave energy leakage around the door viewing window, the exhaust opening and air inlet openings. Microwave energy leakage must not exceed the values prescribed below.
q
NOTES: Leakage with the outer case removed - less than 5 mW/cm2. Leakage for a fully assembled oven (�Before the latch switch (primary) is interrupted�) with the door in a slightly opened position - less than 4 mW/cm2.
