PROCEDURE FOR POWER OUTPUT MEASUREMENT
The power output specification 1500W 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:
1. Fill one beaker ( glass or plastic ) with 2.11 pints ( one litre ) of tap water
at about 68ºF ( 20ºC ) 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 cold cavity.
3. Version 2.0 Press the Manual Function Pad to enter Manual Mode
Version 3.0 Press the lower RH function pad below the display to enter
Manual Mode
Set Time to 1 minute 3 seconds, Power to 100% and Fan to 0%.
Press the Start pad and wait until the counter reaches zero.
4. Take the beaker out immediately stir the water with a plastic implement
and measure the water temperature.
Calculate the temperature rise of water in the beaker.
The temperature rise of the water should be within the following range:
Temperature Rise
27ºF ( 15ºC ) Minimum
36ºF ( 20ºC ) Maximum
Ensure the oven is cold before commencing the test
Note:
Power Output is affected by the line voltage under load.
For correct Power Output measurement the line voltage under load must be correct.
Test procedure:
Changing the Oven Profile
In order to carry out the test the oven PREHEAT
must be set to OFF[ V3.0 ] or 0ºF[ V2.0 ] to switch
off the convection heaters and the Manual
controls must be set to ON [ V3.0 ] or PROGRAM/
MANUAL[ V2.0 ]
When the test is completed the oven must be
returned to its original settings or the appropriate
MenuKey can be used to reset the oven
automatically.
See Appendix 6 for changing the Oven Profile
Manual Mode
If the manual mode
screen does not
appear it must be
changed in the
