Which of the following is an undesirable dynamic characteristic of an instrument ?
Correct answer: D. Time lag
- A. Reproducibility
- B. Dead zone
- C. Static error
- D. Time lag
Explanation
Time lag delays an instrument's response to a changing input, making it a harmful dynamic characteristic. Reproducibility and static error describe steady-state performance, while dead zone is generally treated as a static nonlinearity.
