A line of three-wire differential levels goes from benchmark Gloria to benchmark Carey. The length of the line was determined to be 2199 m. The instrument had a stated compensator accuracy of ±0.3″. The instrument-rod combination had an estimated reading error of ±1 mm per km. The instrument is found have a inclined collimation error of 1.0 mm per km so the sight distances were kept to approximately 50 ± 5 m. If the observed difference in elevation is 15.601 m, what is the estimated error in the final elevation difference?
