3-12 Options and Hardkey Functions
Beam (BM) Off Target: An “X” in this column indicates that the laser
beam from the other head is not being detected on the PSD of the
laser head. This could be due to a beam adjusted in such a manner
that the beam isn't hitting the target, a blocked laser beam, or an
internal error in the laser head. When the laser head is in this state no
data is being acquired. First make sure that the laser beam is properly
adjusted so it hits the PSD of the opposite head. Refer to “Center the
Laser Beams” on page 4-42 for more information. If the adjustment
isn't the problem, make sure the laser beam isn't being blocked by an
obstacle (e.g. cable, dirt or grease on the laser and PSD lenses, dust
particulate in the air, etc.). Contact CSI Customer Support if you are
unable to resolve the problem.
Invalid Calibration (Not currently used): An “X” in this column
indicates that the factory set calibration values have become
corrupted. Contact CSI Customer Support if you experience this
problem.
Non-Linear Region: An “X” in this column indicates that laser beam is
hitting the PSD outside an imaginary limit (boundary) specified at the
factory. This could mean that some of the laser beam is hitting the
PSD and some of the beam is partially off the PSD. It could also
mean that the entire laser beam is hitting on the PSD, but that some
of the beam is hitting the PSD beyond the imaginary limit. When the
laser head is in the is state, data is still being acquired and accepted
since the laser heads can not tell which situation is occurring Make
sure that the laser beam is properly readjusted so it hits the PSD of
the opposite head. Refer to“Center the Laser Beams” on page 4-42
for more information. Contact CSI Customer Support if you are
unable to resolve the problem.
Out-Of-Sync: An “X” in this column indicates that both laser heads are
not synchronized with each other. This could result when the laser
beam is off the target, momentarily as the beam first comes onto the
PSD, or it could be due to an internal error inside the laser head.
When the head is in this state, no data is being acquired. Make sure
that the laser beam is properly readjusted so it hits the PSD of the
opposite head. Refer to “Center the Laser Beams” on page 4-42 for
more information. Contact CSI Customer Support if you are unable
