NOTE: The power output specification, 1200W on this
model is measured with IEC measurement. The power
output is measured with two(2) liters water is equiva-
lent to 1200W in measurement with IEC, when mea-
sured with the following power output.
(1)1. Fill two beakers, one liter of tap water respec-
tively
2. Use an accurate thermometer and measure each
water temperature respectively.
(2) Place beakers side by side in center of the
ceramic tray.
(3) Close the door,set the “TIME” for two minutes.
Touch the “START” key and heat the water for
exactly two minutes.
(4)Take the beakers out, immediately stir the water
and measure the water temperatures respectively.
(5) Calculate the temperatures rise of water in each
beaker. Then calculate the average value of the two
temperature rises.(Ģt)
(6) The teperature rise shall be in the following range;
Average Temp. Rise
Minimum 15.4°C
Maximum 18.8°C
Power output is affected by the line voltage under load.
(7) For correct Power output measurement, the line
voltage under load must be 120±2 Volts.
