What is zero drift in an instrument?
A. The tendency of the instrument to produce inconsistent results over time.
B. The ability of the instrument to measure small changes in the input signal.
C. The change in the instrument’s output signal over time when the input signal is zero.
D. The degree of closeness of the measured value to the true value of the signal.

Explanation: Zero 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 zero. This can be caused by factors such as aging components or changes in temperature or humidity and can affect the accuracy of the instrument’s measurements.
