Kalibrointitaulukko refers to a calibration table or chart. It is a document that records the results of a calibration process for a measuring instrument or device. This table typically lists the nominal or true values against the corresponding readings obtained from the instrument being calibrated. The purpose of a calibration table is to document the accuracy and traceability of the instrument.

A calibration table is essential for quality control and assurance. It allows users to understand how much an instrument deviates from the true value across its measurement range. This deviation, often referred to as the error or correction, can then be applied to subsequent measurements made with the instrument to improve their accuracy. For instance, if a thermometer reads 20.5°C when the standard is 20.0°C, the calibration table would record this difference. This information can then be used to correct future readings.

The content of a typical calibration table includes the instrument's identification details, such as its model, serial number, and calibration date. It will also specify the standards used for calibration, including their own calibration status and traceability. The table then presents the measured values, often in a series of points across the instrument's operating range. For each point, both the standard value and the instrument's reading are recorded, along with the calculated error or correction. Sometimes, uncertainties associated with the calibration are also included. Calibration tables are crucial for industries where precise measurements are vital, such as manufacturing, science, and healthcare, ensuring that instruments are reliable and meet regulatory requirements.
