The power output specification, 1425W on this model is established under IEC 705 standard
method. This method is only workable in Laboratory controlled conditions.
An approximate method is as follows:
PROCEDURE FOR POWER OUTPUT MEASUREMENT
To carry out this test the Icon Pads need to be switched to ENGINEERING MODE PROGRAMS
See previous page
1 Fill one beaker ( glass or plastic ) with one litre ( 1.78 pints ) of tap water
( at about 20ºC/68ºF ) and measure the water temperature.
( Use a thermometer with a
1
/
10
, 0.1 degree gauge ).
2 Place the beaker in the centre of the cavity.
3
Tim Hortons Ovens only
With the oven in ENGINEERING MODE Press Pad 01 (Cake) and any Load Pad ( Quarter,
Half, Full ) Wait until the counter reaches zero.
4 Take the beaker out immediately stir the water with a plastic implement and measure the
water temperature.
5 Calculate the temperature rise of water in the beaker. The temperature rise of the water
should be within the following range:
Temperature Rise
15ºC ( 27ºF ) Minimum
20ºC ( 36ºF ) Maximum
Note:
Power Output is affected by the line voltage under load. For correct Power Output
measurement, the line voltage under load must be correct.
