In measurement systems, what is the purpose of calibration?

Calibration is a critical process in measurement systems that ensures the accuracy and reliability of the readings obtained from instruments. The primary purpose of calibration is to eliminate errors that can arise due to various factors such as instrument drift, environmental changes, or manufacturing variances. By calibrating an instrument, you adjust its output to align with known reference standards, thereby increasing the precision of its measurements.

This process involves comparing the instrument's readings to a standard that is known to be accurate, and making adjustments as necessary. This is essential in fields where precise measurements are crucial, as even minor inaccuracies can lead to significant errors in decision-making, safety, and quality control. Calibration helps maintain the integrity of measurement systems, ensuring that the data collected is valid and reliable for analysis and operational use.
