Measurement troubleshooting
Problem
Possible causes
Action
Beam strength fluctuating
•
Environment is outside operating temperature range
•
Ensure XM environment is between 10 °C and 40 °C
Beam strength fluctuating during
machine movement
•
Normal behaviour at increased speed between targets
•
Receiver clamp block is not tight
•
No action required (this has no effect on metrology)
•
Tighten the receiver clamp block
All data looks noisy
•
XM system fixed loosely
•
Improve the rigidity of the system mounting
All data
(except for roll)
looks noisy
•
The unit is positioned in turbulent air environment
•
Reposition the unit to avoid the turbulent air or stir the air with a fan
Noisy straightness measurement
•
None or short-term averaging is used
•
Select long-term averaging in Capture
Drift (most significant for linear
measurements)
•
The system and/or the set-up is not thermally stabilised
•
Perform a number of runs before capturing data for the machine axis to thermally
stabilise
•
Ensure the laser/receiver are warmed up as per recommendations before testing
(see
•
If the receiver battery has been replaced, follow the
recommendations.
•
Avoid excessive handling of the launch/receiver to avoid body heat exchange
•
If using custom mounting parts, ensure they are suitable to avoid thermal growth
