MEASUREMENT AND TEST
2. MICROWAVE RADIATION TEST
PROCEDURE
1. Prepare Microwave Energy Survey Meter, 600cc glass beaker, and
glass thermometer 100°C (212°F ).
2. Pour 275cc ± 15cc of tap water initially at 20 ± 5 ° C (68 ± 9° F) in the
600 cc glass beaker with an inside diameter of approx. 95 m m(3.5 in.).
3. Place it at the center of the tray and set it in a cavity.
4. Close the door and operate the oven.
5. M easure the leakage by using M icrowave E nergy S urvey M eter w ith
dual ranges, set to 2450M Hz.
(1)
Measured radiation leakage must not exceed the value prescribed
below. Leakage for a fully assem bled oven with door norm ally
closed m ust be less than 4mW /cm
2
.
(2) When measuring the leakage, always use the 5 cm (2 in.)
space cone with probe. Hold the probe perpendicular to the
cabinet and door. Place the space cone of the probe on the
door, cabinet, door seem, door viewing screen, the exhaust air
vent sand the suction air vents.
(3) Measuring should be in a counter-clockwise direction at a rate
of 1 in./sec. If the leakage of the cabinet door seem is unknown,
move the probe more slowly.
(4) 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 closer than 2 in. from any metal. If it does not, erroneous reading may result.
WARNING
•
M ake sure to check the m icrow ave leakage before and after repair of adjustm ent.
•
A lw ays start m easuring of an unknow n field to assure safety for operating personnel from m icrow ave energy.
•
D o not place your hands into any suspected m icrow ave radiation field unless the safe density level is know n.
•
C are should be taken not to place the eyes in direct line w ith the source of m icrow ave energy.
•
S low ly approach the unit under test until the radiom eter reads an appreciable m icrow ave leakage from
the unit under the test.
