ristikkäiskalibrointi

Ristikkäiskalibrointi, also known as cross-calibration, is a process used to relate the measurements of one instrument to those of another, often a more precise or reference instrument. This is particularly relevant when a new instrument needs to be integrated into a system where other instruments are already in use, or when an instrument's performance needs to be verified against a standard. The core idea is to measure the same physical quantity using both instruments simultaneously or under identical conditions and then establish a mathematical relationship between their readings. This relationship can be a simple linear correction factor or a more complex function, depending on the characteristics of the instruments.

The purpose of ristikkäiskalibrointi is to ensure consistency and comparability of measurements across different instruments. This is crucial in many fields, including scientific research, industrial process control, and environmental monitoring, where data from various sources must be combined or compared accurately. By performing ristikkäiskalibrointi, users can account for any systematic biases or differences in sensitivity between instruments, thereby improving the overall reliability of the collected data. The process typically involves a series of measurements across a range of values, followed by data analysis to determine the calibration function.
