driftfejl

Driftfejl, also known as drift error, is a type of systematic error that occurs in measurements and observations. It is characterized by a gradual and continuous deviation from the true value over time. Unlike random errors, which can fluctuate unpredictably, drift errors consistently shift the measured value in one direction.

Driftfejl can arise from various sources, including instrument instability, environmental factors, or changes in the system being measured. For example, a thermometer that gradually loses accuracy over time due to thermal expansion or contraction of its components would exhibit drift error.

To mitigate drift errors, several techniques can be employed. Regular calibration of instruments can help maintain their accuracy. Additionally, using instruments with low drift characteristics or implementing drift compensation algorithms can minimize the impact of drift errors. Understanding and accounting for drift errors is crucial in fields such as metrology, engineering, and scientific research to ensure the reliability and accuracy of measurements.
