Touch Trigger Probe Repeatability
Another possible cause of error is shanking, when the probe contacts the part
with the shank of the stylus and not the tip. The measuring system will assume
the hit was taken with the tip and large errors will occur. Increasing the diameter
stylus ball increases the ball/stem clearance and lessens the likelihood of
shanking. The Effective Working Length (EWL) is the depth that can be
achieved by the stylus before its stem fouls (or shanks) against the feature.
Generally the larger the ball, the greater the EWL. Using a larger stylus ball also
reduces the effect of surface finish of the component being inspected, however,
the largest ball which can be used is limited by the smallest hole to be measured.

The probe should be treated as a precision measuring instrument. Keep it free of
dirt and handle it with care to ensure it maintains it’s size and shape.
The stylus is made of industrial quality ruby that is very hard and provides good
wear resistance. The stylus ruby tip should always be kept free of contaminants.
A one micron (0.000040 inch) piece of grime causes a one micron measurement
error.
