For accurate measurement with the
Vee Fixture, the axis of the Vee must
be aligned parallel to the axis of probe
traverse and at the proper distance
from the Pocket Surf unit so that the
probe skid and stylus travel precisely
along the top (“crown” or “high spot”)
of the workpiece.
The Vee Fixture was set, at the factory,
for correct parallelism and distance to ac-
commodate its normal range of cylindrical
workpiece sizes from 1/8"/13.2mm up to
approximately 1"/25mm in diameter. If,
for some reason, the factory setting has
been disturbed, or another workpiece

be repositioned with a little effort.
2. Place the 1/8"/3.2mm diameter Setting
Pin, PS-145, in the Vee and proceed
to measure it like a regular workpiece
(steps 3 and 4 from previous page).
Closely observe the path of the probe
skid and stylus on the Setting Pin during
the traverse.
