Working with POSITIP – First Steps
Before you start
You can cross over the reference marks after every switch-on.
REF appears in the input line on the screen when all the reference
marks have been crossed over. If you set a new datum, POSITIP
automatically stores the new relationship between axis slide posi-
tions and display values.
Working without reference mark evaluation
You can also use POSITIP without crossing over the reference
marks — simply press the soft key
No REF .
Note that if you do not cross over the reference marks,
a new datum point you set will not be stored. This
means that after a power interruption the relationship
between axis slide positions and display values cannot
be restored.
