MOVE PROBE ALONG SHADEDAREA( )AROUND EXHAUSTOPENINGS(as shown)AND AROUNDAIR INLET OPENINGPROCEDURE FOR MEASURING MICROWAVE ENERGY LEAKAGEWARNINGCheck for radiation leakage after every servicing. Shouldthe leakage be more than 2 mW/cm 2 (1mW/cm 2 forCanada) inform PASC, PSC, or PCI immediately.After repairing or replacing any radiation safety device,keep a written record for future reference, asrequired by D.H.H.S. and Health and Welfare Canadaregulation. This requirement must be strictly observed.In addition, the leakage reading must be recorded onthe service repair ticket while in the customer’s home.NOTE: The U.S. Government standard is 5 mW/cm 2 while inthe customer’s home. 2mW/cm 2 stated here is our ownvoluntary standard. (1mW/cm2 for Canada)1. Equipment*Electromagnatic radiation monitor*Glass thermometer 212 OF or 100 OC*600cc glass beaker2. Procedure for measuring radiation leakageNote before measuring.(1) Do not exceed meter full scale deflection. Leakage monitorshould initially be set to the highest scale.(2) To prevent false readings the test probe should be held by thegrip portion of the handle only and moved along the shaded areain Figure no faster than 1 inch/sec (2.5cm/sec).(3) Leakage with the outer panel removed ...... less than 5mW/cm2 .(4) Leakage for a fully assembled oven with door normally closed...... less than 2mW/cm2 (1mW/cm 2for Canada).(5) Leakage for a fully assembled oven [Before the latch switch(primary) is interrupted] while pulling the door ...... less than2mW/cm2 .(A) Pour 27515cc (9ozss1/2oz) of 20O5 OC (68 O9 O F) water in abeaker which is graduated to 600cc, and place in the center of theoven.(B) Set the radiation monitor to 2450MHz and use it following themanufacturer’s recommended test procedure to assure correctresults.(C) When measuring the leakage, always use the 2 inch (5cm) spacersupplied with the probe.(D) Tap the start pad or set the timer and with the magnetron oscillating,measure the leakage by holding the probe perpendicular to thesurface being measured.(1) Measurement with the outer panel removed.Whenever you replace the magnetron, measure for radiation leakagebefore the outer panel is installed and after all necessary componentsare replaced or adjusted. Special care should be taken in measuring around the magnetron.WARNING(2) Measurements with a fully assembled oven.After all components, including outer panel are fully assembled,measure for radiation leakage around the door periphery, thedoor viewing window, the exhaust opening and air inlet openings.3. Record keeping and notification after measurement(A) After any adjustment or repair to a microwave oven, a leakage read-ing must be taken. Record this leakage reading on the repair ticketeven if it is zero.A copy of this repair ticket and the microwave leakage reading shouldbe kept by repair facility.Avoid contacting any high voltage parts.(B) Should the radiation leakage be more than 2 mW/cm2 (1mW/cmfor Canada) after determining that all parts are in goodcondition, functioning properly, and genuine replacementparts as listed in this manual have been used, immediatelynotify PASC, PSC or PCI.4. At least once a year, have the radiationmonitor checked for calibration by itsmanufacturer.01-035- 19 -WARNINGAVOID CONTACTING ANY HIGH VOLTAGE PARTS.
