Webcalibrated artifact is then used to determine the measurement errors for lengths that are particularly sensitive to errors in the tracker’s angular encoders and optical and mechanical geometrical alignment. Due to time and economic constraints, re-calibration of the scale bar during the extensive performance tests is not typically performed. WebScale targets are printed on Brunson scale material, and provide a target pattern at a precisely known distance from the reference end of the scale. These are often used in conjunction with our Invar Kits to create known calibration artifacts for 3D measuring instruments, such as theodolite systems. tradeable astd
