The primary goal of kalibrointikäytäntöihin is to compare the performance of a measurement instrument with a reference standard of known accuracy. This comparison allows for the identification and correction of any systematic errors or deviations in the instrument's readings. The reference standard is typically a more accurate or higher precision instrument that has been calibrated against an even more accurate standard, often referred to as a primary standard.
1. Preparation: The measurement instrument and the reference standard are prepared for calibration. This may include cleaning, adjusting, or configuring the instruments to ensure they are in optimal working condition.
2. Comparison: The measurement instrument is compared with the reference standard under controlled conditions. This comparison may involve measuring the same quantity using both instruments and recording the results.
3. Analysis: The results of the comparison are analyzed to identify any discrepancies between the measurement instrument and the reference standard. This analysis may involve statistical methods to determine the magnitude and significance of any errors.
4. Correction: Based on the analysis, corrections are made to the measurement instrument to improve its accuracy. This may involve adjusting the instrument's settings, replacing worn components, or applying calibration factors to the readings.
5. Documentation: The results of the calibration process are documented, including the comparison results, any corrections made, and the new calibration status of the measurement instrument. This documentation is crucial for maintaining the traceability of measurement results and ensuring compliance with regulatory requirements.
Kalibrointikäytäntöihin is typically performed at regular intervals, as specified by the manufacturer or regulatory standards, to ensure that the measurement instrument remains accurate over time. Proper calibration practices help maintain the integrity of measurement data, enabling reliable decision-making and ensuring the safety and quality of products and processes in various industries.
