Self test - Humidity calibration

Selfttest
Your SCC will carry out an automatic
self test and adjust itself perfectly to
the set-up conditions and the altitude.
Softwater:
7°dH, 12,5°F, 8,7°E, 125ppm, 1,25 mmol/l
Humidity calibration is part of the self test
Different food items cook best at their specific humidity level and specific temperature.
Vegetables are steamed, bread is baked in dry heat and roast is cooked at a specific humidity and mostly above
100°C (212°F)
To be able to achieve this task the unit must have stored specific pressure values for cold and dry, steam and com-
bination conditions. These values are stored on the PCB and SD Card.

Self test and humidity calibration is broken down into many different steps.
During humidity calibration the differential pressure sensor P1 determines pressure values at all fan speeds and all
directions.

The self test comprises a component test, hu-
midity calibration, determination of the boiling
point and volume setting of the steam genera-
tor (SCC only).
Remove all accessories, packing material and
fastening aids from the cabinet.
To start the self test the unit (B1, B2 and B4)
must be below 40°C (104°F). Place a closed
flat GN container face down in front of each
fan wheel.
The self test must be completed and can not
be skipped!
