Zeroing the Displays
Absolute Zero
On many prints, dimensions are measured
from one or two surfaces of the workpiece. By
setting the readout’s absolute display to zero
at a well-chosen surface, you can enter
the part’s dimensions directly
from the print, using absolute
presets.

of the metal workpiece. The absolute position
display will automatically be set to zero at the
workpiece edge.
