kalibrovat

Kalibrovat is a Czech verb meaning to calibrate, that is, to adjust and verify the accuracy and performance of a measuring instrument or system so that its readings are correct and traceable to reference standards. Calibration usually involves comparing instrument outputs with known reference values and establishing a calibration curve or correction factors.

Calibration is used in laboratories, manufacturing, healthcare, and many service sectors. It differs from adjustment, which may involve altering the instrument to reduce error, and from verification, which checks whether an instrument still meets stated specifications without changing it. A calibrated instrument provides traceability to the International System of Units (SI) through reference standards and calibration certificates.

Process and documentation: select an appropriate reference standard; perform measurements with the instrument under defined conditions; compare results to reference values; determine measurement error and, if needed, compute correction factors or a calibration curve; apply any necessary adjustments; re-check performance; and document the results in a calibration certificate. Ongoing calibration schedules depend on usage, risk, and regulatory requirements.

Common contexts include thermometers, balances, gauges, and optical or electronic instruments. Calibration can be performed in-house or by accredited laboratories, in accordance with standards such as ISO/IEC 17025, which emphasizes traceability and competence.

Etymology: the term kalibrovat derives from the broader technical vocabulary surrounding caliber and calibration, and is used in Czech and other Slavic languages to describe the process of aligning measurement instruments with reference standards.
