MICROWAVE OVEN TECH SHEET CAUTION Disconnect from Electrical Supply Before Servicing Unit PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID PROSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY A. Do not operate or allow the oven to be operated with the door open. B. Make the following safety checks on all ovens to be serviced before activating the Magnetron or other microwave source, and make repairs as necessary. 1. Interlock operating. 2. Proper door closing. 3. Seal and sealing surfaces ( Arcing, wear and other damage.) 4. Damage to or loosening of hinges and latch. 5. Evidence of dropping or abuse. C. Before turning on microwave power for any service test or inspection within the microwave generating compartments. check the magnetron. Waveguide or transmission line. And cavity for proper alignment, integrity and connection. D. Any detective or mis-adjusted components in the interlock, monitor, door seal, and microwave generation and transmission systems shall be repaired. replaced. or adjusted by producers. designed in this manual before the oven Is released to the owner. E. A microwave leakage check to verify Compliance with the Federal performance Standard should be performed on each oven prior to release to the owner. F. Do not attempt to operate the oven if the door glass is broken.

(continuity checks only) OUTPUT POWER OF MAGNETRON CAUTION MICROWAVE RADIATION PERSONNEL SHOULD NOT ALLOW EXPOSURE TO MICROWAVE RADIATION FROM MICROWAVE GENERATOR OTHER PARTS CONDUCTING MICROWAVE ENERGY. The output power of the magnetron can be measured by performing a water temperature rise test. Equipment needed: * Two 1-liter cylindrical borosilicate glass vessel (Outside diameter 190 mm) * One glass thermometer with mercury column NOTE: Check line voltage under load. Low voltage will lower the magnetron output. Make all temperature and time tests with accurate equipment. 1. 2. Fill the one liter glass vessel with water. Stir water in glass vessel with thermometer, and record glass vessel's temperature ("T1", 10 +_ 1 C). 3. After moving the water into another glass vessel, place it in the center of the cooking tray. Set the oven to high power and operate for 47 seconds exactly. ( 3 seconds included as a holding time of magnetron oscillation) 4. When heating is finished, stir the water again with the thermometer and measure the temperature ( "T2"). 5. Subtract T1 from T2. This will give you the water temperature rise. ( T ) 6. The output power is obtained by the following formula; Output = 4.187x1000x T+0.55xMcx(T2-T0) 45 : Heating Times (sec) 42 ( 3 seconds included as a holding time of magnetron oscillation.) 4.187 : Coefficient for water 1000 : Water ( cc ) T : Temperature Rise (T2-T1) T0 : Room Temperature Mc : Cylindrical borosilicate glass weight 7. Normal temperature rise for this model is 9.9 C to 10.3 C at 'HIGH'. NOTE 1: Variations or errors in the test procedure will cause a variance in the temperature rise. Additional power test should be made if temperature rise is marginal. NOTE 2: Output power in watts is computed by multiplying the temperature rise (step 5) by a factor of 91 times the of centigrade temperature.
