MEASUREMENT WITH OUTER CASE 
REMOVED 
• 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 
 
 
 
 
 
 
 
 
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, the exhaust opening, 
and air inlet openings. 
• Microwave energy leakage must not exceed the values 
prescribed below. 
NOTE: Leakage with the outer case removed less than 
3 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 1 mW/cm

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 1.0 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 
WARNING : AVOID CONTACTING ANY
HIGH VOLTAGE PARTS 
(Magnetron, H.V. Transformer, 
H.V. Capacitor, H.V. Cable Ass’y, 
H.V. Fuse)
