peruskalibrointi

Peruskalibrointi, often translated as "basic calibration" or "reference calibration," refers to the initial or fundamental calibration process for a measuring instrument. This is typically performed by the manufacturer or a specialized calibration laboratory before the instrument is put into service. The purpose of peruskalibrointi is to establish a traceable baseline of accuracy for the instrument, ensuring it meets its specified performance standards.

This initial calibration establishes the relationship between the instrument's readings and known, certified reference standards. These standards are themselves traceable to national or international metrology institutes. The process involves a series of measurements under controlled conditions to verify that the instrument's output is within acceptable tolerances for its intended application.

Peruskalibrointi is crucial for ensuring the reliability and validity of measurements. It forms the foundation for subsequent calibrations, which are performed periodically to maintain the instrument's accuracy over time. Without a proper peruskalibrointi, the instrument's measurements may be inaccurate, leading to incorrect decisions, product defects, or non-compliance with regulations. The results of a peruskalibrointi are documented in a calibration certificate, which provides evidence of the instrument's accuracy at the time of calibration.
