passed, better after one hour operation.
To avoid strange light the lid has to be
closed during the dark adjustment.

Automatically all eight sensitivity levels
(V0...V7) are calibrated in succession at
simultaneous display of the dark value.
The function cannot be interrupted. After com-
pletion the program returns to the utility
