5-10 Check for Microwave Leakage

5-10-1 Procedure for Measurement of Microwave Energy Leakage
1) Pour 275 ±15cc of 20¡C±5¡C ( 68¡F±9¡F )
water in a beaker which is graduated to 600cc,
and place the beaker in the center of the oven.
2) Start to operate the oven and measure the leakage
by using a microwave energy survey meter.
3) Set survey meter with dual ranges to 2,450MHz.
4) When measuring the leakage, always use the 2
inch spacer cone with the probe. Hold the probe
perpendicular to the cabinet door. Place the
spacer cone of the probe on the door and/or
cabinet door seam and move along the seam,
the door viewing window and the exhaust
openings moving the probe in a clockwise
direction at a rate of 1 inch/sec. If the leakage
testing of the cabinet door seam is taken near a
corner of the door, keep the probe
perpendicular to the areas making sure that the
probe end at the base of the cone does not get
closer than 2 inches to any metal. If it gets closer
than 2 inches, erroneous readings may result.
5) Measured leakage must be less than
4mW/cm2, after repair or adjustment.
5-10-2 Note on Measurement
1) Do not exceed the limited scale.
2) The test probe must be held on the grip of the handle, otherwise a false reading may result when the
operator's hand is between the handle and the probe.
3) When high leakage is suspected, do not move the probe horizontally along the oven surface; this may
cause damage to the probe.
4) Follow the recommendation of the manufacturer of the microwave energy survey meter.
5-10-3 Record keeping and notification after measurement
1) After adjustment and repair of a radiation preventing device, make a repair record for the measured
values, and keep the data.
2) If the radiation leakage is more than 4mW/cm
functioning properly and the identical parts are replaced as listed in this manual, notify that fact to ;
CENTRAL SERVICE CENTER
3) At least once a year have the microwave energy survey meter checked for accuracy by its manufacturer.
