Working with the TNC 124 – First Steps
Before you start
You must cross over the reference marks after every switch-on.
From the positions of the reference marks, the TNC automatically re-
establishes the relationship between axis slide positions and
display values that you last defined by setting the datum.
Setting up a new datum point automatically stores the new relation-
ship between axis positions and display values.
