A method and an arrangement for optimizing the luminance characteristic curve for a display system using a lookup table. Digitized video levels are supplied to this lookup table and are optimized using correction values stored in the lookup table. With suitable means, the luminance characteristic curve can be easily adapted to standards and/or custom specifications. The memory requirement is low, since it is not necessary to provide different lookup tables for different ambient luminosities or selected reproduction models (curves).

A method and a circuit arrangement for controlling the operating point of a cathode ray tube ( ) for use in image technology applications. A video signal ( ) is supplied to both the tube ( ) and to a cathode ray tube model ( ), which the model ( ) uses to emulate a beam current. From the emulated beam current and a measured beam current, a characteristic quantity for adjusting the operating point is determined.

In an accident involving the uncontrolled escape of coolant, a condensate film forms on the power station components. Due to deposited dirt it is conductive, and if the insulation has aged it can cause electrical function defects. That situation is simulated by spraying a test liquid, having a wetting power (surface tension) and a conductivity which correspond to the coolant condensate, onto the electrical power station components. The testing can be carried out on a routine basis at normal pressure and normal temperature during ongoing reactor operation.
