with ATR
• The accuracy with which the position of a prism can be determined with Automatic
Target Aiming (ATR) depends on several factors such as internal ATR accuracy,
instrument angle accuracy, prism type, selected EDM measuring program and the
external measuring conditions. The ATR has a basic standard deviation level of
± 1 mm.
• The following graph shows the ATR standard deviation based on three different
prism types, distances and instrument accuracies.
