MICROWAVE LEAKAGE TEST

CAUTIONS

•Be sure to check microwave leakage prior to servicing the oven if the oven is operative prior to servicing.

•The service personnel should inform the manufacture importer, or assembler of any certified oven unit found to have a microwave emission level in excess of 5 mW/cm2 and should repair any unit found to have excessive emission levels, at no cost to the owner, and should ascertain the cause of the excessive leakage. The service personnel should instruct the owner not to use the unit until the oven has been brought into compliance.

•If the oven operates with the door open, the service personnel should:

-Tell the user not to operate the oven.

•The service personnel should check all surface and vent openings for microwave leakage.

•Check for microwave leakage after every servicing. The power density of the microwave radiation leakage emitted by the microwave oven should not exceed

4 mW/cm2. Always start measuring of an unknown field to assure safety for operating personnel from radiation leakage.

EQUIPMENT

•TESTER (VOLTS-DC, AC, Ohmmeter)

•Microwave survey meter - Holaday HI-1500

HI-1501

-Narda 8100 8200

•600 cc non conductive material beaker (glass or plastic), inside diameter: approx. 8.5 cm (31/2 in.)

•Glass thermometer: 100°C or 212°F (1 deg scale)

MEASURING MICROWAVE ENERGY LEAKAGE

•Pour 275±15cc of 20±5°C(68±9°F) water in a beaker which is graduated to 600 cc, and place the beaker on the center of the turntable.

•Set the energy leakage monitor to 2,450 MHz and use it following the manufacturer's recommended test procedure to assure correct result.

•When measuring the leakage, always use the 2-inch (5cm) spacer supplied with the probe.

•Operate the oven at its maximum output.

•Measure the microwave radiation using an electromagnetic radiation monitor by holding the probe perpendicular to the surface being measured.

Move probe along shaded area.
