Title: How ATR Works in the CR2/CR5
Created: 0000-00-00Last modified: 0000-00-00
The Carlson Software CR2 and CR5 instruments utilize ATR (Automatic Target Recognition) functionality searches to for a prism and precisely position the scope.

Remember that the crosshairs may not, and do not need to be exactly positioned on the centre of the prism – this does not matter. The ATR measures the deviation between the centre of the prism and the crosshairs to display the correct angles in the measurement screen – this speeds up the overall measurement process.  A typical application for the ATR is monitoring; where the use of the ATR saves the surveyor time by accurately and automatically measuring to the centre of prisms.
