Calibrated Artifact
Measure an artifact of certified dimensions (i.e.:
ring gage or gage block).
Ring Gage should be measured as a cylinder.
Gage Block should be measured plane-to-
plane, or point-to-plane (surface point).
N
OTE
: The dimension of calibrated artifacts is
usually specified at a temperature of 20°C
(68°F). If the current temperature is different,
use the Material Temperature Compensation
function in CAM2, or the following formula:
Actual Length = Specified Length*(1 +
CTE*(Current centigrade temperature - 20°C)), where CTE is the
Coefficient of Thermal Expansion of the material in ppm/°C.
E
XAMPLE
:
A 150mm ring gage measured at 25°C made of Steel 1020
will be: 150mm * (1 + 11.7e-6/C*(25°C - 20°C)) = 150.00585 mm
If additional support is required, please contact customer support. When
contacting customer service, please provide the following information:
1 The serial number of the device(s).
2 A copy of the probe calibration log.
3 A copy of the event log.
4 A copy of the Single Point Articulating Test (SPAT).
5 Pictures of the setup.
Diagnosing Laser Line Probe Accuracy Problems
Always diagnose the FaroArm prior to diagnosing the Laser Line Probe.
If the FaroArm is not mounted correctly, or the hard probe is not
accurately calibrated, then the Laser Line Probe will produce inaccurate
results.
Allow the Laser Line Probe to warm-up.
• 60 minutes for version 1 Laser Line Probes
• 30 minutes for version 2 Laser Line Probes
• 15 minutes for version 3 Laser Line Probes
