Chapter 1: Introduction to the FaroArm
FaroArm Probes
Three standard probes, two (2) 6mm Ball and
one (1) Point, are supplied with the FaroArm.
Each ball probe is stamped with the diameter of
the ball (3mm, 6mm, etc.).
The FaroArm’s point of measurement on any
ball probe is the center of the ball. Third-party
feature measurement or quality control software compensates for the
radius of the ball probe. Point probes are only recommended when the
software will not compensate for the radius of the ball probe. The point
probe has an impact on measurement accuracy. The error depends on:
• the width of the point on the probe
• the position and placement of the point on the object
N
OTE: For accurate measuring, you must calibrate the probe. Use
your measuring software to setup and calibrate the probe. See
“Probes” on page 31.
Custom Probes
You may create any size probe to
attach to the FaroArm.
• The FaroArm Probe
thread size is 1¼-20.
• The base of the probe
should follow the shape of
the FARO probes.
Your custom probe should be a
rigid as possible. Any deflection in
the probe will add inaccuracy to the
FaroArm system.

OTE: FARO Technologies Inc. does not guarantee the accuracy of
the FaroArm with the use of a custom probe.
