What is drift in an instrument?
A. The difference between the maximum and minimum values that can be measured by the instrument.
B. The degree of change in the output signal for a given change in the input signal.
C. The tendency of an instrument to give different readings for the same input signal when approached from different directions.
D. The change in the instrument’s output signal over time when the input signal is constant.
Answer:D

The change in the instrument’s output signal over time when the input signal is constant.
Explanation: Drift is a characteristic of an instrument that refers to the change in the instrument’s output signal over time when the input signal is constant. This can occur due to changes in temperature, aging of components, or changes in the environment in which the instrument is used.
