Function of Calibration

Why is calibration important?

Calibrating a device has 3 main purposes:
-Ensures readings from an instrument are consistent with other measurements.
-Determines accuracy of the readings.
-Establishes the reliability of the instrument i.e. that it can be trusted.

what-is-calibration

Comparison of a known value from a “standard” to an unknown value from the unit under test. Accuracy of the standard varies but the typical standard will be at least ten (10) times as accurate as the device being tested.

Regular Calibration Provides Confidence

Accuracy changes for all measuring devices over time through normal wear and tear. Changes can also be caused traumatic events like electric or mechanical shock. Working environments with contaminants such as oils, metal chips or chemicals can also affect accuracy. Other significant factors are the quality of the instrument, frequency of use and skill of the user. The end result of no calibration is over confidence and can be a problem for any organization.

Calibration Results

Calibration improves the reliability of measurements to improve product quality and consistency.

Calibrating your instruments saves time and money in re-work or replacement of bad products.
