What is typically the first step in the calibration process?

The first step in the calibration process is to compare instrument readings to a standard. This foundational step establishes a baseline by which the performance of the instrument can be measured. By measuring the instrument against a known standard, technicians can determine the accuracy and performance characteristics of the device in question.

This comparison is crucial because it allows for the identification of deviations from the expected values, which are necessary for subsequent adjustments. Only after establishing how the instrument performs relative to the standard can technicians proceed to make any necessary adjustments or corrections to ensure accuracy.

Following this initial comparison, other important steps like adjusting for environmental conditions, documenting calibration results, and replacing worn components may occur, but without the initial comparison, there would be no way to determine what adjustments are needed or why they are necessary. Thus, this step lays the groundwork for the entire calibration process by providing a clear reference point.
