(C) 1 . Set cooking time to two (2) minutes. (“2 00”
appears in display)
2 . Touch “START” key and operate oven for exactly
two (2) minutes.
(D) 1 . Take out the two bowls at once.
2 . Stir both water with thermometer and measure the
water temperature rise respectively.
(E) 1 . Get temperature rise by calculation the difference
(water temperature after cooking minus initial
temperature) in each bowl.
2 . Then calculate average value(t) of both temperature
rises in degrees centigrade.
3 . Then work out :
Power Output (watt) = 70 x
∆
t
Where
∆
t is an Average Temperature Rise in degrees
centigrade.
(F) Power Output shall be in the following range :
(G) Power Output will be influenced by line voltage of
power supply. Consequently, correct Power Output
must be measured within 120V AC ± 1 volt while
unit is operating.

NOTE
The Power Output specification 1050W on this model
is measured with IEC measurement. The Power Output
is measured with two (2) liters water is equivalent to
1050W in measurement with IEC, when measured with
the following Power Output.
(A) 1 . Fill two test bowls with each 1 liter water respectively.
2 . Use accurate thermometer and measure each
water temperature respectively.
(B) Place the two bowls on glass turntable.
