Reference point detection The reference point of the measuring unit can be detected Data storage The value displayed before the power was turned off and setting values are stored Linear compensation A fixed compensation is applied to the measuring unit’s count value. Compensation amount Standard: 600 um/m (Expanded: 1000 um/m) Segmented error compensation The movement range of the measuring unit with a reference point can be divided into a maximum of 32 sections, and error compensation is performed for each of these sections. Compensation amount: 600 um (at each section) Scaling Scaling factor0.100000 9.999999 Program
