Abstract
Method for zero correction of a measuring device, in particular a flowmeter, wherein a number of zero settings are carried out with the device and/or process in different states. In the case of each of these zero settings, a set of device and/or system parameters is recorded together with the measured zero value and stored in an electronic memory, and in normal operation of the measuring device, a stored set of device and/or system parameters that matches the respectively current system and/or device parameters is sought, so that the measured zero value assigned to this set of parameters is used as the current zero value.
