• If you arc ca librating iI ma chine tool, you w ill probably wa mt o make yo ur measurements
as cl ose as possible to the ar ea where the t oo l meets the workpiece .
• If you are checking the accuracy of a machine's distance measur ing system, you wi ll
prob<lbly
wa nt to make your measurements as d ose as possible to Ihat sys tem, since any
offset between your measurement axis and the di
.. tance mea su ring sys tem's axis may
introduce

You ca n make all l ase r Syste m measuremCnlS for thr ee di fferent axes from on ly t wo se t- upsof the

1.
All th e Optics ha ve been designed around a common centerline, all ow ing complete

For Distance and
Angular mea sureme nt s, you can use all of the same mounting hardware
with
no adjustments be tw een measurements.
2. Measuremen 1S on the " z .. axis can be made from either the "x" or "Y" axis by t urn ing the
Distilnce and
Angular In te rf erol ll eters on their sides, or by using d Turning Mirror for
Straightn ess measurement s. ( See the individual m eas urem ent sections in this User 's G uid e
