The Pocket Surf gage will operate in any one of four different probe positions (see
illustration on next page). Selection of the proper probe position depends on the ap-
plication.
When changing probe positions, gently grasp the probe by its body; never handle the
probe by its skid and stylus end.
Prior to operating the gage, its calibration should be checked. Refer to the
&DOLEUDWLRQ
section for details.
Important:
During the measuring cycle, the probe stylus and skid should be in contact
with a surface, and the setup should be properly aligned (as outlined in the following
sections). Otherwise, any readings obtained are not valid and are not to be used for
measurement or gage performance evaluation purposes.
