2.8.1 Maximum Permissible Error (MPE)
Accuracy specications in the technical data of this manual are stated with
the Maximum Permissible Error (MPE). The Maximum Permissible Error (MPE)
is dened by the ISO 10360-10:2021 as the extreme value of the measure-
ment error permitted by specication for the relevant test, i.e. length meas-
urement. An acceptance test is veried if all measurement errors according
to the relevant test item are smaller than the corresponding MPE specic-
ations. The ISO 10360-10:2021 denes criteria for the repetition of meas-
urements that exceed the MPE values. Typical measurement results of the
Absolute Tracker are half of the relevant MPE values.
2.8.2 Laser Tracker Subsystem Specications

tion in accordance with ISO 10360-10:2021, Annex D.
