POWER OUTPUT MEASUREMENTPOWER OUTPUT MEASUREMENTPOWER OUTPUT MEASUREMENTPOWER OUTPUT MEASUREMENTPOWER OUTPUT MEASUREMENTNOTENOTENOTENOTENOTEThe power output specification, 1050W. on this model ismeasured with IEC measurement. The power output ismeasured with two (2) liters water is equivalent to 1050W.in measurement with IEC, when measured with the followingpower output.(1) Fill two beakers (glass or plastic) with each one liter oftap water (about 20°C) 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. (“200” inthe display window). Touch the “START” key and heatthe water exactly for two minutes.(4) Take the beakers out, immediately stir the water andmeasure 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 ∆tWhere ∆t is an average temperature rise in degreesCentigrade.(6) Power Output shall be in the following range :Average Temperature Rise Power OutputMinimum 19.6°F (10.9°C) 763WMaximum 20.0°F (14.0°C) 980W(7) Power Output is affected by the line voltage under load.For correct Power Output measurement, the line voltageunder load must be 120±1 volts.4 .4 .4 .4 .4 .

(See pages 1 and 6).(b) Make sure the perforated screen and the choke die-lectric of the door are correctly mounted.(2) After the power is applied :(a) Open and close the door to see if the interlock mech-anism operates properly.(b) Check microwave energy leakage with a leakagedetector and confirm the energy leakage should beno greater than 4mW/cm2 to allow for measurementuncertainty.(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 othervisible damage to the oven that may cause microwaveenergy leakage.NOTE :Always keep the seal clean.Always keep the seal clean.Always keep the seal clean.Always keep the seal clean.Always keep the seal clean.(e) Make sure that there are no defective parts in theinterlock mechanism.(f) Make sure there are no defective parts in themicrowave generating and transmission assembly.(especially waveguide).(4) The following items should be checked after the unitis repaired :(a) The interlock monitor switch is connected correctlyand firmly.(b) The magnetron gasket on the magnetron is properlypositioned.(c) Waveguide and oven cavity are intact (no leakage ofmicrowave energy).(d) The door can be properly closed and the safetyswitches work properly.(e) The oven must be stopped when the door is openedor the time is up.The oven must not be operated with any of the aboveThe oven must not be operated with any of the aboveThe oven must not be operated with any of the aboveThe oven must not be operated with any of the aboveThe oven must not be operated with any of the abovecomponents rcomponents rcomponents rcomponents rcomponents removed or bypassed.emoved or bypassed.emoved or bypassed.emoved or bypassed.emoved or bypassed.- 2 -
