Verified Answer
The accuracy of an Electronic Distance Measuring Instrument (EDMI) is ...
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.
± (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.

The accuracy of an Electronic Distance Measuring Instrument (EDMI) is ...
Explanation:
Accuracy Specification:
- The accuracy of an Electronic Distance Measuring Instrument (EDMI) is specified as (a mm b ppm).
- Here, "a mm" represents the constant error in millimeters, and "b ppm" represents the proportional error in parts per million.
Correct Statement:
- The correct statement is: "a remains constant and b varies in proportion to the distance being measured."
- This means that the constant error (a) remains the same regardless of the distance being measured, while the proportional error (b) changes in relation to the distance.
Understanding the Concept:
- The constant error (a) accounts for systematic errors in the EDMI, such as instrumental imperfections.
- The proportional error (b) accounts for errors that increase linearly with distance, such as atmospheric conditions affecting the signal propagation.
Implications:
- The constant error (a) can be calibrated and adjusted to minimize its impact on measurements.
- The proportional error (b) may require correction factors or adjustments based on the distance being measured.
Conclusion:
- Understanding the accuracy specification of an EDMI is crucial for making precise measurements in surveying and construction projects.
- By knowing how the errors (a mm and b ppm) behave, users can account for them effectively and ensure accurate results.
