Figure 1.7-A shows the UCI probe with the flat side of the support
ring to measure on flat surfaces. In Figure 1.7-B the ring has been
removed to measure over a concave sufaces (also used to measure in
hard to reach areas, weld joints, etc). Figure 1.7-C shows the probe
with the “V” side of the ring which is used to measure convex
surfaces.
When you are ready to measure force must
be applied on the UCI probe that has been
ergonomically designed for comfort of use
and ease of operation. The 3 points in
Figure 5 show the positions to better hold
and use the probe; point
1
(top of the
probe) is a large and “soft” area where
you should place the palm of your hand to
gently push down. Point
2 lets you hold the
probe so it doesn’t slide off your fingers or
away from the test piece while point 3
allows you to hold and push down using
fingers from both hands. Using the UCI
probe with one hand only is also possible
even though not recommended.
Figure 1.8: How to apply force
For best results use the support ring in order to maintain the probe
vertical and stable when force is applied. If you need to remove the
ring due to the geometry of the part being tested we suggest that you
use both hands to hold the probe.
