What procedure can increase the range of a total station measurement?

Employing multiple prisms can effectively increase the range of a total station measurement. When multiple prisms are used, the signal reflecting back to the total station becomes stronger and more accurate, allowing for longer distances to be measured with confidence. This is particularly beneficial in scenarios where conditions may be less than ideal, such as poor visibility or when measuring to distant points.

Other methods, such as increasing measurement time, can improve the reliability of readings by allowing more data collection, but they do not address the inherent limitations of the total station's range. Adjusting the baseline angle is also more related to the orientation of measurements rather than extending range. Using a wider lens is generally more about enhancing clarity and field of view rather than increasing measurement distance. Thus, employing multiple prisms is the optimal choice for extending the effective range.
