The sensitivity of an instrument is
- A. The smallest increment in the input that can be detected with certainty
- B. The largest input change to which the instrument fails to respond
- C. Ratio of the change in the magnitude of the output to the corresponding change in the magnitude of the input
- D. Closeness of the output values for repeated application of a constant input
Answer: C. Ratio of the change in the magnitude of the output to the corresponding change in the magnitude of the input
Explanation: Static sensitivity is defined as the ratio of the incremental change in instrument output magnitude (deflection) to the corresponding incremental change in input measured quantity.
