WebDec 7, 2024 · Drift is the gradual shift in the indication or record of the instrument over an extended period of time, during which the true value of the variable does not change. No drift means that with a given input the measured values do not vary with time. Drift is an undesirable quality in instruments. So instruments are properly guarded against drift.
