over Two,” or the Maximum measurement subtracting from the
Minimum measurement divided by two (Max.-Min.)/2.
If any test fails, print the results and repeat the certification two more
times. Print all of the results and contact FARO’s Customer Service by
Phone, Fax or E-Mail. See “Technical Support” on page 93.
Repeatability
Perform the single point repeatability test to check the probe and
repeatability using a hole or a cone. You must use a firmly secured
object with a hole at least 1mm smaller than the ball probe. If a cone
hole is used, extreme care must be taken to ensure that the probe is
seated at each “measurement.”
• Use a calibrated Ball Probe. See “Installing Probes” on page 21 and
“Calibrate Probe” on page 79.
• Run the Single Point Certification command.
1 Measure points in the hole, or cone, from multiple directions.
2 Make sure that you move the joints of the FaroArm while
measuring the points.
3 Do not digitize a point if any of the encoders reach their end stop.
See “Error and Status Indicators” on page 14.
4 Avoid a position where a degree of freedom is lost in the FaroArm.
See “Loss of a Degree of Freedom” on page 50.
