Oftentimes equipment calibration and adjustment are misunderstood and even considered to be the same process. Although both processes work closely together to ensure proper functionality of equipment; they are two separate entities.
One way to specifically see the difference between equipment calibration and adjustment is to go back to the books – the true definition of each process shows how each varies:
Equipment calibration can be defined as the process of comparing values and measurements of an instrument to a specific standard in a controlled environment.
During equipment calibration, the accuracy of the required standard is known, which aids in determining if a piece of equipment will pass or fail each parameter. Parameters in calibration include, test conditions, operating conditions, industry specifications, tolerances, etc. Because the standard is known at the beginning of the equipment calibration process, measurements can be easily compared to the specified standard during calibration. If a piece of equipment were to fail a specific parameter, the calibration process will be repeated and adjustments may be made if necessary.
Adjustment can be defined as the process of altering an equipment’s performance to match a specific accuracy limit.
Before adjustments are made, it is normal for equipment calibration to be carried out first. After adjustments are made to a piece of equipment, calibration will be performed to ensure that the adjustments are within the specified accuracy limit.
Although equipment calibration and adjustment do go hand-in-hand, it is always important to check if your calibration provider offers repairs and adjustments within their calibration services. Often providers will provide these services if necessary, but it may be an added cost. However, using a provider who does offer equipment calibration and adjustment services all together can be extremely beneficial and can decrease you downtime, while ensuring accuracy and reliability of your equipment.
