3 Select the AUXILIARY SWITCH check box, and enter a De-
bounce time if necessary.
4 Select the G
UIDANCE check box to use the guidance feature in
single hole calibration. See “Single Hole Method - Guidance”
on page 34, and “Single Hole Method” on page 37.
5 Click the CREATE NEW button.
The new probe is now current and must be calibrated.
Probe Calibration Overview
Probe calibration is a localized process by which a measurement device
is optimized to perform measurements accurately.
To understand probe calibration, you must first understand the
FaroArm's reference system. The FaroArm is factory calibrated from
the base to the last joint or axis, and the position of this joint is defined
by the coordinate system which originates at the base of the FaroArm.
The last axis of the FaroArm has its own coordinate system, and the
location of the center of the ball probe is reported in the probe's
coordinate system. After the probe's coordinates are established, these
are translated into FaroArm coordinates and you are ready to start taking
measurements.
Measurement accuracy relies on probe calibration under optimal
conditions. If the probe calibration is good, measurements will be
accurate. If the probe calibration is bad, measurements will not be as
accurate. Proper mounting and technique are critical calibration factors.
