FAQ

If you have an issue or question that requires immediate assistance, you can click the button below.

ASK A QUESTION

What happens if the wrong prism constant is set? How do I correct the data?

Using an incorrect prism constant introduces a systematic offset into every distance measurement recorded during the survey. The total station applies the constant as an additive correction to the raw EDM reading, so any error propagates uniformly across all observations. For example, if a −30 mm prism is used but the controller is set to −17.5 mm, every recorded distance will be 12.5 mm too long. To correct the data, calculate Δ = PCactual − PCset and apply the correction to all measured distances. The recommended approach is to update the prism constant in your office software and recompute the project so all coordinates are recalculated automatically.

Are standard circular prisms really more accurate than 360° prisms?

Yes. Standard circular prisms generally provide higher centering accuracy because they use a single precision corner-cube prism. Most 360° prisms consist of multiple prism elements whose alignment tolerances accumulate, resulting in a wider pointing error envelope. However, for robotic topographic surveys, the productivity benefits of omnidirectional tracking usually outweigh the small accuracy difference. Standard prisms remain the preferred choice for control surveys, precision deformation monitoring, and industrial alignment applications.

Can I use prisms from different brands with my total station?

Yes. Cross-brand prism use is technically feasible and widely practiced throughout the surveying industry. The critical requirement is entering the correct prism constant for the specific prism being used. Most measurement errors when mixing brands arise from incorrect prism constant settings rather than optical incompatibility. Particular attention should be paid to Leica's Swiss constant convention, where nominal constants may differ from absolute constants. Always verify the absolute prism constant before configuring a non-Leica instrument.

Why can't my robotic total station lock onto the monitoring prism? How do I troubleshoot it?

Persistent ATR lock failures are typically caused by uncalibrated ATR collimation, contaminated optics, environmental reflections, incorrect tracking mode settings, or a prism that is too small for the observation distance. Begin troubleshooting by cleaning both the instrument lens and prism, manually aiming at the prism center, and attempting a manual lock. If manual lock succeeds, perform the instrument's ATR calibration procedure and retest automatic tracking. For long-range monitoring applications, consider using a larger prism to improve target acquisition reliability.

Why do reflectorless mode and mini-prism readings differ by 5 mm at close range with a steep vertical angle?

This difference is commonly caused by the combination of steep vertical angles and very short measurement distances. In reflectorless mode, the laser beam strikes the target surface obliquely, causing the reflected signal centroid to shift relative to the crosshair aim point. At the same time, a mini-prism that is not perfectly aligned with the instrument can introduce additional cosine-related ranging errors. For critical elevation measurements, minimize vertical angles whenever possible and ensure the prism is accurately leveled and properly oriented toward the instrument.
