2. MICROWAVE RADIATION TEST

PROCEDURES

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 600cc glass beaker with an inside diameter of approx.
95mm(3.5in.).

3. Place it at the center of the tray and set it in a cavity.
4. Close the door and operate the oven.
5. Measure the leakage by using Microwave Energy Survey

Meter with dual ranges, set to 2450MHz.

1) Measured radiation leakage must not exceed the value

prescribed below. Leakage for a fully assembled oven with

door normally closed must be less than 4mW/cm

2

.

2) When measuring the leakage, always use the 5cm(2in.)

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 vents and 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.

CAUTION :
1. Make sure to check the microwave leakage before and after repair of adjustment.
2. Always start measuring of an unknown field to assure safety for operating personnel from microwave energy.
3. Do not place your hands into any suspected microwave radiation field unless the safe density level is known.
4. Care should be taken not to place the eyes in direct line with the source of microwave energy.
5. Slowly approach the unit under test until the radiometer reads an appreciable microwave leakage from the unit

under the test.
