- ALTERNATIVE METHOD -
It is also possible to have ND 780 determine an offset.
This method involves touching the tip of each tool to
a common reference surface. This allows ND 780 to
determine the difference between the length of each
tool.
Move the tool until its tip is touching the reference
surface.
Press the TEACH LENGTH soft key. ND 780 will
calculate an offset relative to this surface.
Repeat the procedure for each additional tool using
the same reference surface.
