Abstract
Atmospheric pressure is allocated to a sensor signal of a pressure sensor as a reference pressure for a piston position in the load change upper dead center position. The sensor sensitivity and, on the basis thereof, the absolute pressure value at arbitrary piston positions is determined from this reference signal and two further sensor signals at prescribed piston positions.
