5-9 Leakage Measuring Procedure
Alignment and Adjustments
5-9-3 Check for Microwave Leakage
( With the opter panel removed)
1. Remove the outer panel.
2. Pour 275±15cc of 20±5ûC(68±9ûF) water in a beaker which is graduated to 600cc, and place the beaker
in the center of the oven.
3. Start the oven at the highest power level.
4. Set survey meter dual ranges to 2,450MHz.
5. Using the survey meter and spacer cone as described above, measure arnear the opening of
magnetron, the surface of the air guide and the surface of the wave guide as shown in the following
photo.( but avoid the high voltage components.) The neading should be less than 5mW/cm
2
.
5-9-4 Measurement Notes
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.
5-9-5 Record Keeping and Special Notification
1. After adjustment and repair of a radiation protection device, record for the measured values, and keep
the data.
2. If the radiation leakage exceeds 5mW/cm2 (after determining that all parts are in good condition,
functioning properly and that central service center identical parts are replaced as listed in this
manual) notify the central repair facility.
3. At least once a year have the Microwave Energy Survey Meter checked for accuracy by its
manufacturer.
