Which of the following judges the accuracy of an instrument ?
Correct answer: C. Static error
- A. Dead zone
- B. Drift
- C. Static error
- D. None of these
Explanation
Static error is the difference between the true value and the value indicated by an instrument under steady conditions, so it directly indicates accuracy. Drift is a gradual change in indication with time, while dead zone is a range in which the instrument gives no response.
