Q9. The accuracy of an Electronic Distance Measuring Instrument (EDMI) is specified as
± (a mm + b ppm). Which one of the following statements is correct?
Answer : Option BExplaination / Solution:
Accuracy of EDMI is generally stated in terms of constant instrument error and measuring
error proportional to distance being measured.
± (a mm + b ppm)
The first part in this expression indicates a constant instrument error that is independent of
length of line measured. Second component is distance related error.
