Electronic Distance Measuring Equipments - Problem 3

If the error in EDM measurements is ±0.021ft in 1000ft. distance. What is the relative accuracy of the EDM?

Solution:

\begin{equation} RA = \frac{e}{B} \end{equation}

\begin{equation} RA = \frac{0.021ft.}{1000ft.} \end{equation}

\begin{equation} RA = \pm \frac{1}{47619} \end{equation}

Answer: \begin{equation} RA = \pm \frac{1}{47619} \end{equation}
