What does the term "calibration" refer to in maintenance?

The term "calibration" in maintenance specifically refers to the process of adjusting and setting equipment to ensure it operates accurately and provides precise measurements. Calibration is critical in environments where equipment must meet specific standards, as it directly impacts the reliability and accuracy of the performance of instruments or machinery. This process typically involves comparing the readings from a device against a known standard and making necessary adjustments to align the device’s output with this standard.

While cleaning equipment is important for maintaining performance, it does not directly affect measurement accuracy. Testing equipment is part of routine maintenance but focuses on functionality rather than making adjustments to achieve accurate performance. Replacing old equipment is a different maintenance process entirely that does not pertain to calibration. Therefore, the best definition for calibration in this context is indeed about the adjustments made to ensure accurate performance.
