Why should I Calibrate my equipment?

Requirements

Most instruments are typically subjected to some fairly rough treatment — bouncing around in the vehicle, dropped on site, knocked against hard objects, etc. Even if they’re treated carefully and not knocked about, changes in ambient temperatures, humidity levels and deteriorating component tolerances will cause a shift in any electronic measuring equipment readings over time.

The reason why we advise regular calibration and if required, adjustments, to ensure the outputs are accurate and therefore dependable. Calibration is defined as a measurement, referenced to a ‘known’ standard. Calibration gives you confidence in the measurements being made, provides proof of validated measurements and ultimately enables more time to be spent on core work, rather than having to retest if there isn’t complete confidence in the results.

When testing and calibration is required, there is only one proper way to do it. Unless full range and full scale calibration is completed against validated standards and the data recorded, then the time and expense of doing so is wasted. Everything else, such as self-checks, is false comfort only.

Consequences

As a reputable business, you need to understand the consequences of inaccurate measurements brought on by the use of un-calibrated or inaccurately calibrated meters. For critical applications, the consequences could be one hundred times the cost of the meter or calibration, or even more. On top of that, your reputation is put on the line.

The consequences of not calibrating can be quite detrimental to a business. The key factor is the integrity of the measured record if it is ever called up as evidence in a court of law. All Master Calibrators ensure that proper procedures are followed, including ISO17025, which outlines laboratory and calibration standards. This removes any uncertainty associated with the reliability and measurement accuracy of your Meter. This provides a traceable reference if you are ever faced with having to prove your innocence in a court of law when it comes to the validity of Test Results.

When checking any critical measurement, you are often dealing with people’s safety and you are carrying an extended duty of care.
