Anchoring the Segments
If you anchor the beginning of the first segment at a known location on the
encoder, then the segment boundary values will be the actual physical
distances from the anchor point, as shown below.
Anchoring the segments is optional: if you don’t do it, the segment boundary
values may be meaningless to you (although they are understood by the
readout).
Pressing this softkey puts the start of Segment 1 at the current
tool location. To anchor the segments correctly, move the encoder
in the negative count direction as far as it will go, then press

Note: If you anchor Segment 1 in a different place after you have established
the compensation values, then the entire compensation table will be shifted to
the new anchor location, as shown below.
