Course Summary:

Since the beginning of the surveying profession, there have always been standards of length. 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 is 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. In this course, specifications and recommended procedures for establishing calibration baselines are described in detail.

Learning Objective:

• Responsibility for baselines and costs
• Calibration range
• Base line layout
• Monumentation
• Appendix A: Suggested equipment for establishing a calibration baseline
• Appendix B: Field measurement standards, specifications and procedures

Review the quiz before studying the course.
