Abstract:
A method for adjusting a switching threshold of a touch probe, which has a touch element, comprising:deflecting said touch element out of a position of repose; based on said deflecting of said touch element, causing a defined change in a measurable system parameter; adjusting a switching threshold to a value dependent on the value of said measurable system parameter at said position of repose of said touch element, wherein said switching threshold is determined from a reference value, which is variable in increments and which is compared with the value of said measurable system parameter at said position of repose of said touch element and said reference value is corrected by one increment at a time, based on the value of said measurable system parameter at said position of repose of said touch element, if the reference value deviates from the value of said measurable system parameter at said position of repose of said touch element.
