Chapter 1: Introduction to the FaroArm
Normal Maintenance
The FaroArm is a precision instrument that contains many sensitive
components, and it should be handled with care. Take the following
precautions to prevent problems from developing with your system:
• Place a dust cover over the FaroArm when not in use.
• Clean with a dry dust cloth. For heavy dirt buildups, use a very
small amount of warm water and gently clean the Arm. Be
very careful not to bend the Arm while cleaning.
• Check the cables for damage to outside insulation, connectors,
and pins.
• Do not lubricate the FaroArm.
The FaroArm is calibrated at FARO’s factory and should only need to
be recalibrated after the unit has been subjected to a shock that removes
surface material or causes bending. Periodical certifications tests
should be completed to certify the FaroArm accuracy and repeatability.
See “Certification” on page 18.
Mounting Stiffness Test
The FaroArm is portable and can be mounted in a variety of
environments. The FaroArm is counterbalanced, and it is the nature of
counterbalancing that reaction forces may exist in the mounting due to
the applied forces generated by the counterbalancing mechanism. The
reaction forces will result in deformations in the mounting, which
degrade the performance of the FaroArm if the deformations are
sufficiently large.
The primary forces encountered due to counterbalancing are translation
and torsion. These forces are illustrated below. The forces can be
further described along or about the three major axes of a coordinate
system at the mounting base. The translation forces (F) along the axes
and the moments (M) about the axes result in deformations of the base.
The deformation due to the translation force can be measured. You
must apply forces (lb. or N) using a calibrated load cell at the mounting
