errors can be excluded to a large extent.
Special features of VAST probe system
Setting the measuring force
The measuring force has to be set for measuring probe systems such
as VAST. The value of the measuring force must be entered in the
measuring software
➤
operating instructions for the measuring soft-
ware.
The measuring force must be set prior to calibrating the probe. Set
the measuring force for each probe individually if required.
Why does the measur-
ing force have to be
set?
During probing, the probe element causes changes of the workpiece
form. The extent of these form changes influences the precision of
the calculated values. In order to avoid falsified measuring data, the
measuring force should be adapted to the characteristics of the work-
piece material.
