The Pocket Surf gage is calibrated using
the Reference Specimen and the
EPL-1681 Riser Plate supplied with the
PocketSurf Kit.
Set the Parameter Selection Switch to
“R
a
”. The other two parameters, R
max
and R
z
will automatically be calibrated
when R
a
is calibrated.
Set the Traverse Length Switch to
position 5 because a full 5 cutoffs are
required for proper calibration of the
instrument.

Note:
When calibrating with a General purpose
Probe, Groove Bottom Probe, the Transverse Chisel
Probe or a Small Bore Probe, the probe should be in
the 180° “Extended” position (as shown above). The
Parallel Chisel Probe must be in the 90° or 270°
position and the setup rearranged so that the probe
will traverse the Specimen in the direction of the
arrow.
1. To elevate the Pocket Surf base to
the same height as the surface of
the Reference Specimen, place the
Pocket Surf unit on the Riser Plate so
that the two “V’s” on the bottom of the
Pocket Surf Unit sit in the shallow
recesses of the Riser Plate. Align
the Reference Specimen so that the
gage probe will traverse across it in
the direction of the double-ended
arrow. Take a reading from the center
of the specimen.
