The measurement uncertainty of the spatial length “U
L
” is defined as the
deviation of a measured length from its nominal value. This deviation is
specified as a function of the shortest distance between the Laser Tracker
and the measured length. The length can be up to 6 m and is positioned per-
pendicularly to the laser beam. At the end of the reference length are two
fix-mounted spheres (sphere radius between 15 mm and 20 mm). The sphere
centres represent the nominal distance. The measured distance between the
sphere centres is calculated by using the scan data of all four T‑Scan sides.

> 8.5 m (27.9 ft) ±26 mm + 4 mm/m (±0.0010 in + 0.00005 in/ft)
The measurement uncertainty of the sphere radius “U
R
” is defined as the
deviation of a measured sphere radius from its nominal value.

U
R
< 8.5 m (27.9 ft) ±50 mm (0.002 in)
U

> 8.5 m (27.9 ft) ±16 mm + 4 mm/m (±0.0006 in + 0.00005 in/ft)
The measurement uncertainty of the sphere surface “U
S
” is defined as the
total value of deviation of a sphere surface from the best-fit sphere. This
value is calculated from all measured points. The measurement uncertainties
are specified as a function of the distance between the Laser Tracker and the
sphere. The specification assumes a reference sphere with a radius between
10 mm and 50 mm. The sphere radius and the sphere surface are calculated
by using the data of all four T‑Scan sides.

S
±85 mm + 1.5 mm/m (±0.0033 in + 0.00002 in/ft)
The measurement uncertainty of plane surface “U
P
” is defined as the total
value of deviation of a plane surface from the best-fit surface. This value is
calculated from all measured points. The plane surface is calculated by using
the data of all four T‑Scan sides.
