Method for detecting and correcting zero offset of pressure gauge, involves separating pressure input of pressure to be measured by valve, where pressure input and another pressure input are short-circuited by compensating valve

The method involves separating a pressure input of a pressure to be measured by a valve (7), where the pressure input and another pressure input are short-circuited by a compensating valve (9). A same pressure to be measured is applied by short-circuiting of the pressure-inputs. An actual pressure value of a pressure gauge (2) is detected as a correction pressure value. The correction pressure value is compared with a tolerated tolerance area.
