CAUTIONS• Be sure to check microwave leakage prior toservicing the oven if the oven is operative prior toservicing.• The service personnel should inform themanufacture importer, or assembler of any certifiedoven unit found to have a microwave emission levelin excess of 5 mW/cm2 and should repair any unitfound to have excessive emission levels at no cost tothe owner and should ascertain the cause of theexcessive leakage. The service personnel shouldinstruct the owner not to use the unit until the oven hasbeen brought into compliance.• If the oven operates with the door open, the servicepersonnel should:- Tell the user not to operate the oven.• The service personnel should check all surface andvent openings for microwave leakage.• Check for microwave leakage after every servicing. Thepower density of the microwave radiation leakageemitted by the microwave oven should not exceed4 mW/cm 2. Always start measuring of an unknown fieldto assure safety for operating personnel from radiationleakage.EQUIPMENT• TESTER (VOLTS-DC, AC, Ohmmeter)• Microwave survey meter- Holaday HI-1500HI-1501- Narda 81008200• 600 cc non conductive material beaker (glass orplastic), inside diameter: approx. 8.5 cm (31/2 in.)• Glass thermometer: 100°C or 212°F (1 deg scale)MEASURING MICROWAVE ENERGYLEAKAGE• Pour 275±15cc of 20±5°C(68±9°F) water in a beakerwhich is graduated to 600 cc, and place the beakeron the center of the turntable.• Set the energy leakage monitor to 2,450 MHz anduse it following the manufacturer's recommendedtest 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 andelectromagnetic radiation monitor by holding theprobe perpendicular to the surface being measured.Move probe along shaded area.Probe scanning speedLess than 2.5 cm/sec. ( 1 in/sec)• It should not exceed 4 mW/cm 2.7-2MICROWAVE LEAKAGE TEST
