Question:
The ratio of maximum displacement deviation to full scale deviation of the instrument is called _______.
The ratio of maximum displacement deviation to full scale deviation of the instrument is called _______.
Show Hint
Linearity quantifies how much the actual instrument curve deviates from an ideal straight-line behavior.
Updated On: Jun 24, 2025
- static sensitivity
- dynamic deviation
- linearity
- precision or accuracy
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand linearity in instruments
Linearity defines how closely the output of an instrument follows a straight-line relationship with input over the full range.
Step 2: Mathematical definition
It is defined as: \[ \text{Linearity} = \frac{\text{Maximum Deviation}}{\text{Full Scale Value}} \] Step 3: Why other options are incorrect
- Static sensitivity: ratio of output to input change.
- Precision: closeness of repeated measurements.
- Dynamic deviation: error due to time-varying inputs.
