What is the purpose of maintenance tolerances in device calibration?

The purpose of maintenance tolerances in device calibration is to ensure accuracy within a specified range. These tolerances define the allowable limits of deviation from the true value that a measurement device can have while still being considered reliable and accurate for its intended use. By establishing these tolerances, organizations can maintain quality control and ensure that calibration processes keep devices functioning optimally over time.

When maintenance tolerances are strictly followed, it assures operators that measurements taken by the device will remain consistent and trustworthy, which is crucial in applications where precision is paramount. This focus on accuracy helps to minimize measurement errors that could lead to incorrect data interpretation or defective product outputs.
