Error Messages
E1 — Motor did not start.
E2 — Motor failed to accelerate to
proper operating speed.
E3 — Motor failed to maintain proper
operating speed.
E4 — Excessive traverse length.
E5L — Traverse Length 1 or 3
selected for R
z
.
If error message “E5L” is displayed
on the digital readout, it indicates that
the Traverse Length Switch is set for
positions 1 or 3 and the Parameter
Selection Switch is set for R
z
. Due
to DIN standards, R
z
can only be
calculated on the 5 cutoff position.
If error message “E1” or “E4” is
displayed on the digital readout, it
usually indicates an internal electrical
or mechanical malfunction requiring
repair; see the
Repairs
section on
page 26.
Maintenance and Troubleshooting
(continued)
If error message “E2” or “E3” is displayed on
the digital readout, it usually indicates that a
malfunction has occurred in the probe
traverse which prevented or interfered with
normal movement. One or more of the
following conditions may be the cause:
1. An obstruction or excessive pressure on
the probe or the Probe Holding Block.
2. Dust, dirt or other contamination around
the probe skid and stylus, and/or in and
around the bearing and its slot beneath
the Probe Holding Block.
3. A weak battery (but not weak enough to
cause the “low” battery signal to be
displayed on the readout).
To remedy these conditions:
1. Make sure the workpiece is clean and
dry, and the surface to be measured is
free from gross defects.
2. Make sure the gage and workpiece
setup is properly adjusted, with the
surface to be measured at
approximately the same elevation as
the base of the PocketSurf unit and
parallel to it, and the Reference Line on
the Probe Mounting Block parallel to the
bottom edge of the PocketSurf housing
(as outlined in the
Gage Operation
section on page 9).
