Abstract
The discovered temperature of the feeler is regularly determined and is recorded together with the associated calibrating data at this temperature. Temperature correction data for the feeler are established from this historic collection consisting of temperature values and of calibrating data. This temperature correction data can be used during a measurement at the respective temperature. This method avoids a separate and complicated setting of the temperature of the feeler or of the entire coordinate measuring device for the calibration.
