To perform measurements using the Angle/Distance Sets - Dir/Rev method to eliminate centering errors in the horizontal and vertical circles in precision data collection.
When measuring a point using the Angle/Distance Sets - Dir/Rev method, the instrument will use the specified angle sequence to perform repeated measurements. The sequence of four measurements constitutes one set. The sequence consists of two measurements to the backsight in direct and reverse position of the total station and two measurements to the foresight point in direct and reverse position of the total station. The order of measurements in the sequence is customizable. Multiple foresight points can be included into the set of Angle/Distance Sets - Dir/Rev measurements.
Go through the Set Collection wizard to setup and perform measurements using this method.
