2. POWER OUTPUT MEASUREMENT
NOTE
The power output specification, 900W on this model is measured
with lEC measurement. The power output is measured with two(2)
liters water isequivalentto900W inmeasurement with lEC, when
measured with the following power output.
(A)
1. Fill twotest bowls with eachl Iiter water respectively.
2. Use accurate thermometer and measure each water
temperature respectively.

Set cooking time to two (2) minutes. ("2 00" appears in
display)
Touch START key and operate oven for exactly two (2)
minutes.
Take out the two bowls at once.
Stir both water with thermometer and measure the water
temperature rise respectively.
Get temperature rise by calculating the difference (water
temperature after cooking minus Initial temperature) in
each bowl.
Then calculate average value(t) of both temperature rises
in degrees centigrade.
Then work out;
Power Output (watt) = 70 x At
Power output shall bein the following range:

Power Output will be influenced by line voltage of power
supply. Consequently, correct power output must be
measured within 240 VAC+2 volts while unit is operating.
