Calibrating the Displacement of the Positioner 

A recalibration of the displacement is only necessary when the positioner (or parts of it) or the 

E-625 of a calibrated system was replaced. A calibrated, external measuring device is used to 

recalibrate the position sensor back to the accuracy specified in the original measurement 

protocol.
