WIRING DIAGRAM
PROCEDURE
A) Prepare Microwave Energy Survey Meter, 600cc glass breaker, glass thermometer 100˚C or 212˚F.
B) Pour 275cc ± 15cc of tap water initially at 20 ± 5˚C (68 ± 9˚F) in the 600cc beaker with an inside diameter of
approx. 8.5 cm (3.5 in).
C) Place it at the center of the tray and set it in a cavity.
D) Close the door and operate the oven.
E) Measure the leakage by using microwave energy survery meter with dual ranges, set to 2,450 MHz.
– Measured radiation leakage must not exceed the values prescribed below.
• Leakage for a fully assembled oven with door normally closed must be less than 4mW/cm
2
.
– When measuring the leakage, always use the 5cm space cone with probe. Hold the probe perpendicular to
the cabinet, door. place the space cone of the probe on the door, cabinet, door seam,along the seam, the
door viewing window, the exhaust air vents, the suction air vents.
– Measuring shonld be in a counter-clockwise
direction at a rate of 1 inch/sec. If the leakage of
the cabinet door seam is unknow, move the
probe more slowly.
– When measuring near a corner of the door, keep the probe perpendicular to the areas making sure the probe
end at the base of the cone does not get closet than 2 inches from any metal.
If it does, erroneous reading may result.
