8.1. Equipment•••• Electromagnatic radiation monitor•••• Glass thermometer 212 °F or 100 °C•••• 600cc glass beaker8.2. Procedure for measuringradiation leakageNote before measuring.•••• Do not exceed meter full scale deflection. Leakage monitorshould initially be set to the highest scale.•••• To prevent false readings the test probe should be held bythe grip portion of the handle only and moved along theshaded area in Figure no faster than 1 inch/sec(2.5cm/sec).•••• Leakage with the outer panel removed ...... less than5mW/cm 2 .•••• Leakage for a fully assembled oven with door normallyclosed ...... less than 2mW/cm 2 .•••• Leakage for a fully assembled oven [Before the latch switch(primary) is interrupted] while pulling the door ...... less than2mW/cm 2 .1. Pour 275 ± 15cc (9ozs ± 1/2oz) of 20°C ± 5°C (68 ± 9°F)water in a beaker which is graduated to 600cc, and place inthe center of the oven.2. Set the radiation monitor to 2450MHz and use it followingthe manufacturer´s recommended test procedure to assurecorrect results.3. When measuring the leakage, always use the 2 inch (5cm)spacer supplied with the probe.4. Tap the start pad or set the timer and with the magnetronoscillating, measure the leakage by holding the probeperpendicular to the surface being measured.8.2.1. Measurement with the outer panelremoved.Whenever you replace the magnetron, measure for radiationleakage before the outer panel is installed and after allnecessary components are replaced or adjusted. Special careshould be taken in measuring around the magnetron.8.2.2. Measurements with a fullyassembled 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 inletopenings.8.3. Record keeping andnotification after measurement1. After any adjustment or repair to a microwave oven, aleakage reading must be taken. Record this leakagereading on the repair ticket even if it is zero.A copy of this repair ticket and the microwave leakagereading should be kept by repair facility.8.4. At least once a year, have theradiation monitor checked forcalibration by itsmanufacturer.8 PROCEDURE FOR MEASURING MICROWAVE ENERGYLEAKAGE18NN-S453WF
