) 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/cm

At least once a year have the microwave energy survey meter checked for accuracy by its
manufacturer.
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 4mW/cm
2
.
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.
Maximum allowable leakage is 5mW/cm
