Touch Trigger Probe Repeatability
The touch trigger probe is designed to give optimum results when the probe hits
are taken perpendicular to the probe body (perpendicular to the axis of the
stylus). Wherever possible make hits perpendicular to the probe body. Probe hits
taken parallel to the probe body (along the axis of stylus) give results that are not
as repeatable as those taken perpendicular to the axis. Probe hits neither perpen-
dicular nor parallel to the probe body give results that are less repeatable as
those taken parallel to the probe body. Probe hits taken parallel to the stylus axis,
but at an angle to the probe body, are not repeatable and should be avoided if
possible.
Probe configurations causing triggering forces which are neither parallel nor
perpendicular to the probe body should be avoided.
