Testing/ Analysis/ Calibration

Testing/ Analysis/ Calibration


Calibration is a comparison between a standard measurement and the measurement using a peculiar instrument. Naturally, the accuracy of the standard should be ten times the accuracy of the measuring instrument being tested. Nevertheless, the accuracy ratio of 3:1 is agreeable by most of the standards organizations.

The accuracy of all measuring devices deteriorates over time. This is commonly caused by usual wear and tear. However, changes in accuracy can also be induced by mechanical or electric shock, or a dangerous manufacturing environment.
