orientations throughout the working volume of the Edge. This test is a method for
determining articulating measurement machine accuracy.
• Use a calibrated ball probe. See “Installing Probes” on page 53 and
“Compensate Probe” on page 181.
• Run the Sphere to Sphere, or Point to Point command. See “Sphere to Sphere”
on page 118, or “Point to Point” on page 113, or “Plane to Plane” on
page 116.
1 Measure points on each feature, from multiple directions. Ensure that you
digitize points on the entire Sphere or Plane surface.
2 Make sure that you move the joints of the Edge 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 36.
4 Avoid a joint position where a degree of freedom is lost in the Edge. See
“Loss of a Degree of Freedom” on page 77.
The specifications of your Edge are listed on the label to the right of the battery
pack slot.

OTE: For optimum performance, correctly mounting and operating the Edge
is very important. For more information, see “Edge Performance Verification
Checklist” on page 89.
Loss of a Degree of Freedom
In a working volume of the Edge there can be a loss of a degree of freedom
(natural rotation of each joint). With this loss, temporary bending occurs on the
transfer tubes of the Edge causing a movement of the probe position that cannot
be recorded by the Edge’s encoder system. Measurement results taken in these
