• Look at the before and after results. Click the Ye s button to generate and
save a detailed report of the test to a comma-separated values text file (*.csv
file), or the No button to save the new arm compensation.
The new arm compensation will remain in your Quantum until changed or reset.
Click the Reset button to restore the FARO Factory compensation.
Repeat SPAT
Repeat the SPAT with the compensation cone or conical socket in a different
location. This will verify the new arm compensation.
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).
NOTE: 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.
EXAMPLE: A 150 mm ring gage measured at 25°C made of Steel 1020 will be:
150
mm * (1 + 11.7e-6/C*(25°C - 20°C)) = 150.00585 mm
