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

Explanation: Span 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 at the full-scale range. This can also be caused by factors such as aging components or changes in temperature or humidity and can affect the accuracy of the instrument’s measurements.
