5-9 Leakage Measuring Procedure

5-9-1 Equipment
1. Microwave Energy Survey Meter
2. Glass beaker, 600cc
3 Mercurial or digital thermometer 100ûC or 212ûF
5-9-2 Procedure for Measurement of Microwave Leakage
1. Pour 275±15cc of 20±5ûC (68±9ûF) in toA 600cc graduated beaker. Place the beaker in the center of the
oven.
2. Start the oven and measure the leakage using a microwave energy survey meter.
3. Set survey meter ( 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 on the door seam and move the probe along
the viewing windows and exhaust openings. Move the probe at about 1 inch per second.
If the leakage from door seam is measured near a corner, keep the probe perpendicular, making sure
the probe end(at the base of the cone) does not gt closer than 2 inches to any metal (otherwise,
erroneous readings readings will result).
5. The measured leakage must be less than 5mW/cm
