If you are using electrical test instruments, you expect them to be accurate. But there are instances when an event rendered your instrument less accurate or maybe even unsafe, or when two meters used for the same measurement significantly disagree. In these instances, then there is probably a need for equipment calibration or test equipment calibration.

Calibration is the process of establishing the relationship between a measuring device and the units of measure. This is done by comparing a device or the output of an instrument to a standard having known measurement characteristics. For many operations, the quality of the calibration needs to be known and is quantified by an uncertainty estimate for the calibration. This is so important for the scientific community and manufacturing operations that it has been proposed that an evaluation of the measurement uncertainty was added as part of the calibration process.

Calibration can be called for with a new instrument, when a specified time period is elapsed, when a specified usage has elapsed, when an instrument has had a shock or vibration which potentially may have put it out of calibration and whenever observations appear questionable. Calibration services are designed to help the makers and users of precision instruments achieve the highest possible levels of measurement quality and productivity. On the other hand, a calibration software helps you manage a complete history of your measurement devices, instruments, and gages. A calibration software generates calibration schedules and alerts you to failed and past due calibrations. To help you identify sources of measurement variation, a calibration software provides complete statistical and graphical analysis of your measurement system.

If done properly, the use of calibration services and calibration software can ensure safe and reliable instrument use to get the accurate results you need. It is not just a matter of fine-tuning, but a form of quality assurance.
