WARNING1. Adjustment of Primary latch switch, Second-ary latch switch and Short switch.(A) When mounting Primary latch switch,Secondary latch switchand short switch to door hook assembly, mount the Primary latchswitch, the Secondary latch switch and the short switch to thedoor hook assembly as shown in table.NOTE: No specific adjustment during installation ofPrimary latch switch, Secondary latch switch andshort switch to the door hook is necessary.(B) When mounting the door hook assembly to the ovenassembly, adjust the door hook assembly by moving it in thedirection of arrow in the illustration so that the oven door will nothave any play in it. Check for play in the door by pulling the doorassembly. Make sure that the latch keys move smoothly afteradjustment is completed. Completely tighten the screws holdingthe door hook assembly to the oven assembly.(C) Reconnect the short switch and check the continuity of themonitor circuit and all latch switches again by following thecomponents test procedures.2. Measurement of microwave outputThe output power of the magnetron can be determined by performingIEC standard test procedures. However,due to the complexityof IEC test procedures, it is recommended to test the magnetronusing the simple method outlined below.Necessary Equipment:*1 liter beaker *Glass thermometer*Wrist watch or stopwatchNOTE: Check the line voltage under load.Low voltage willlower the magnetron output. Take the temperaturereadings and heating time as accurately as possible.(A) Fill the beaker with exactly one liter of tap water.Stir the waterusing the thermometer and record the beaker’s temperature.(recorded as T1).(B) Place the beaker on the center of glass cook plate.Set the oven for High power and heat it for exactly one minute.(C) Stir the water again and read the temperature of the beaker.(recorded as T2).(D) The normal temperature rise at High power position for eachmodel is as shown in table.MEASUREMENTS AND ADJUSTMENTS* For continued protection against radiation hazard,replace only with identical replacement parts(For touchm o d e l s P a r t N o .
