Chapter 5: Accuracy
ISO 10360-8 Standard
Annex D of the ISO 10360-8 standard requires one distance test. The test result is
an error and has a Maximum Permissible Error (MPE).
Quantum Calibration
The FaroArm Manager software has commands that allow you to perform tests
that certify the accuracy and repeatability of your Quantum. The Single Point
Repeatability Test (SPAT) allows you to test the Quantum using a hole. Use
measuring software such as CAM2
Measure to test the volumetric accuracy.
The values measured in all of these calibrations include 100% of the measured
points. We will always refer to this as the “Max. minus Min. over Two,” or the
Maximum measurement subtracting from the Minimum measurement divided by
two (Max.-Min.)/2.
PForm - Sphere Probing Form Error. The operator
measures a sphere with the Quantum probe. The
error is maximum distance of any point from the
best-fit sphere.
LDia - Sphere Location Diameter Error. The
operator measures a sphere with the Quantum
probe from multiple orientations. The error is the
diameter of the spherical zone containing the
centers of the measured spheres.
EUni - Unilateral Distance Error. The operator
measures two sphere, or two points, with the
Quantum probe. The error is the difference
between the measure and actual length between the
spheres or points.
LDia - Sphere Location Diameter Error. The
operator measures a sphere with the Quantum
probe from multiple orientations. The error is the
diameter of the spherical zone containing the
centers of the measured spheres.
