Below are some issues issues that can degrade accuracy while measuring with the FaroArm:
- Do not mount to any type of wooden surface or do not mount to optical cables (as Vibraplanes), because the steel sheet on top of the tables is thin and deflects.
- Folding tripods using the stabilizing struts are unstable.
- Heavy-duty stands with wheels down and pins up are unstable.
- Part deformation due to excessive clamping force.
- Measuring with Point Probes.
- Measuring with chipped, loose or cracked ball probes.
- Measuring with probe extensions. The extensions will deflect.
With the Laser Line Probe
- Do not drag the probe over the FARO Compensation Plate during the plane measurement. Lift the probe in between points to avoid scratching the surface of the plate.
- Poor probe compensation technique. Do not do short sweeps with the FARO Laser Line Probe during compensation.
- Dirty lens. Make sure to clean the top and bottom lenses with the cloth from the FARO Laser Line
- Probe Case. Dirt and grease on either lens can cause poor results.
- Measuring close to an end stop can induce unwanted stress.
- Extending the arm out as far as it can go can cause unnecessary stress.
- Or repositioning the device using the Move Device Position command.
- Excessive vibration in the surrounding area can produce unwanted results.
- Rapid changes in ambient temperature can cause errors in the arms automatic temperature compensation.
- Measuring using poor techniques; minimum number of measured points per feature, moving while recording individual points and small coverage area.
Special Note: If the arm is mounted on granite table or cart, do not measure objects that are not mounted to the granite table or cart.
