Drift is commonly used in measuring instruments and current meters. Learn more about drift instrumentation.

In measurement equipment, drift is a measurement error that indicates an undesirable situation in which the displayed or supplied value changes slowly and continuously, even though all conditions are constant.

For example, while there is no change in temperature during measurement, slight increases will be seen in the measured value.

The deterioration of the inside of the measurement device mainly causes it.

The current flow in a semiconductor in the electric field is known as Drift Current.

When the voltage is applied to the semiconductor, the electrons and holes called charge carriers will move to generate current.
