Electronic Distance Measuring Equipments - Problem 4

If the error in EDM measurements is ±0.016ft in 10ft. distance. What is the relative accuracy of the EDM?

Solution:

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

\begin{equation} RA = \frac{0.016ft.}{10ft.} \end{equation}

\begin{equation} RA = \pm \frac{1}{625} \end{equation}

Answer: \begin{equation} RA = \pm \frac{1}{625} \end{equation}
