METHOD FOR CHECKING A MEASURING DEVICE

摘要

A method for testing a measuring device using a reference measuring device, which is connected to a fieldbus system in a plant, to which fieldbus system, and a fieldbus access unit is connected. While testing the measuring device the measuring device remains connected to the fieldbus system and the measured values transmitted from the measuring device via the fieldbus system during the testing are transmitted by means of the fieldbus access unit to an evaluation unit, which evaluation unit is connected with the reference device, in order to compare the measured values of the measuring device with reference measured values of the reference measuring device.
