Chapter 1: Introduction to the FaroArm

Keep in mind that given the vast range of colors, textures and finishes,
there is no exact science for these Line Probe Settings that work best on
a particular surface. Finding the optimum settings may require some
practice.
Additional Considerations
• First, if accuracy is not an issue, even failing probe calibration will
not prevent you from using the Laser Line Probe to show the concept
of gathering point clouds quickly and easily, directly into software
applications. The ScanArm does use the new probe calibration, even
if it fails.
• Second, if the probe calibration does fail, you should look at the probe
calibration log to see by how much. If the error is acceptable, you
should be able to scan effectively for medium accuracy applications.
• Third, if you need to measure in a high accuracy application, or you
have a requirement that the probe calibration pass, make sure you
allow the Laser Line Probe to warm-up for the amount of time
recommended for your model. See “Diagnosing Laser Line Probe
Accuracy Problems” on page 71.
Calibration and Certification
The FaroArm is designed to endure the typical stress and impact loads
of a “factory floor” measuring tool, as well as survive multiple
transportation cycles while maintaining its accuracy throughout its
usable life. In order to fully appreciate what is meant by “Lifetime
Calibration,” you must first understand several basic concepts of
measurement equipment.
Calibration versus Certification
In most cases the terms “calibration and certification” are used together,
and are often mistakenly used interchangeably. This generally occurs
because traditional Coordinate Measuring Machines are often calibrated
every time they are certified. In reference to the FaroArm, there are two
types of calibration: the arm calibration and the probe calibration.
