POWER OUTPUT MEASUREMENT NOTE The power output specification, 1000 W on this model is measured with IEC measurement. The power output is measured with two (2) liters water is equivalent to 1000 W in measurement with IEC, when measured with the following power output. (1) Fill two beakers (glass or plastic) with each one liter of tap water (about 20oC) and measure the water temperature. (Use a thermometer with a 1/10 degree gauge). (2) Place the beakers side by side in the centre of the glass tray. (3) Close the door, set the “TIME” for two minutes. (“2 00” in the display window.) Touch the “START” key and heat the water exactly for two minutes. (4) Take the beakers out, immediately stir the water and measure the water temperature respectively. (5) Calculate the temperature rise of water in each beaker. Then calculate the average value of two temperature rises. Output power can be calculated by the equation; Power Output (W) = 70 x Dt Where Dt is an average temperature rise in degrees Centigrade. (6) Output shall be in the following range : AverageTemperature Rise Power Output Minimum 10.9oC 763W Maximum 14.0oC 980W Power Output is affected by the line voltage under load. (7) For correct Power Output measurement, the line voltage under load must be 120± 2volts. -- 2 -- (1) Before the power is applied : (a) Open and close door several times to make sure the primary interlock switch, the interlock monitor switch and the door sensing switch operate properly. (Listen for the clicking sound from the switches.) Make sure the interlock monitor switch closes after the primary interlock switch is opens when the door is opened. (See pages 1 and 6) (b) Make sure the perforated screen and the choke dielectric of the door are correctly mounted. (2) After the power is applied : (a) Open and close the door to see if the interlock mechanism operates properly. (b) Check microwave energy leakage with a leakage detector and confirm the energy leakage is below 5 mW/cm2. (3) Do not operate the unit until it is completely repaired, if any of the following conditions exists: (a) Door does not close firmly against the cavity front. (b) The hinge is broken. (c) The choke dielectric or the door seal is damaged. (d) The door is bent or warped, or there is any other visible damage to the oven that may cause microwave energy leakage. NOTE : Always keep the seal clean. (e) Make sure that there are no defective parts in the interlock mechanism. (f) Make sure there are no defective parts in the microwave generating and transmission assembly. (especially waveguide). (4) The following items should be checked after the unit is repaired : (a) The interlock monitor switch is connected correctly and firmly. (b) The magnetron gasket on the magnetron is properly positioned. (c) Waveguide and oven cavity are intact (no leakage of microwave energy). (d) The door can be properly closed and the safety switches work properly. (e) The oven must be stopped when the door is opened or the time is up. The oven must not be operated with any of the above components removed or bypassed. 5.
