Accuracy values are reported to a statistical confidence of 95% (k=2). They do not include the errors associated with the normalisation of the readings to a material temperature of 20 °C.

Between 4 and 6 metres

  • The performance specification for linear, angular and straightness measurement will be the same between 4 m and 6 m as it is between 0 m and 4 m.
  • The performance specification for roll measurement between 4 m and 6 m range will be:
Roll
Accuracy±0.01A ±10.0 μrad
(A = roll error (µrad))
Resolution0.12 μrad
Measurement range±500 µrad
Accuracy values are reported to a statistical confidence of 95% (k=2). They do not include the errors associated with the normalisation of the readings to a material temperature of 20 °C. Measurement beyond 4 m range requires good alignment between the XM launch and receiver. If misalignment causes received laser signal strength to fall below 4% of the maximum, CARTO software will inform the user that better alignment is required.

Over 6 metres

  • The performance specification for linear and angular measurement will be the same between 6 m and 8 m as it is between 0 m and 4 m.
  • The performance specification for straightness measurement between 6 m and 8 m is yet to be verified.
  • The performance specification for roll measurement between 6 m and 8 m is yet to be verified.
