backsight Sentence Examples
- The surveyor took a backsight on the previous benchmark to determine the height of the rod.
- The backsight reading helps establish the level of the instrument and reduce errors in leveling.
- Before starting a level loop, it's crucial to establish a stable backsight.
- The target for the backsight should be at a known elevation to serve as a reference point.
- If the backsight distance is too long, it can affect the accuracy of the leveling process.
- A level with a longer backsight distance requires more iterations to achieve the desired precision.
- Taking multiple backsight readings from different positions ensures a more reliable average value.
- The backsight should be free from obstructions or any factors that could hinder line-of-sight.
