Establishment of Calibration Baselines

Course Summary

The calibration of electronic distance measuring instruments involves the determination or verification of instrument constants and the assurance that the measured distances meet accuracy specifications. Although it not necessary to utilize a measured distance to determine or verify instrument constants, the verification effort is reduced when an accurately measured distance can be used. However, to assure that the measuring capabilities of an instrument have not significantly deteriorated, a known distance of high accuracy or preferably, a sequence of distance of high accuracy or, preferably, a sequence of distances forming a calibration range or baseline is required. Specifications and recommended procedures for establishing calibration baselines are described in detail.
