Leica Absolute Tracker And PCMM Specs

Leica Absolute Tracker accuracyFeatureBenefitThe measurement uncertainty of a coordinate “U xyz” isdefined as the deviation between a measured coordinate and thenominal coordinate of that point. This measurement uncertainty isspecified as a function of the distance between the laser trackerand the measured point.All accuracies are specified with Leica Geosystems precision1.5” Red Ring Reflectors, measurement mode of 1 second perpoint under stable environmental conditions and a maximumdistance of 40 radial meters from the measurement sensor. Allspecifications are stated in maximum permissible error (MPE).Typical results are half the MPE.U xyz – Full Range(Full Range Definition: 360° horizontally, ± 45° vertically)AT901-B, AT901-MR, AT901-LR± 15 µm + 6 µm/m(±0.0006” + 0.00007”/ft)Robust construction andsuperior thermal stabilitywith homogenous internaldesign and non-heat emittingtracker sensor headThe AIFM or “AbsoluteInterferometer” combinesthe absolute measurementfrom the ADM with thealmost instantaneous updaterate of the interferometerto produce themost accurate, stable,technologically maturedistancing unit we haveever createdContinuous on-specoperation in tough industrialenvironments with no needfor frequent compensationroutines; a yearly calibrationis all your Leica AbsoluteTracker will ever needWaiting for the tracker to“lock-on” is now a thing ofthe past.
