Calibration is the activity of comparing an unknown measurement to a measurement of higher accuracy. Calibration exists to enable worldwide uniformity of measurements.
It is a necessary part of processes such as manufacturing, testing, and quality assurance, where various measurement instruments are utilised.
For locally produced goods to be internationally competitive, the use of the calibrated measuring instrument at all levels of industrial or manufacturing production should not only be a requirement but an absolute priority.
What is the Purpose of Calibration?
There are four main reasons for having instruments calibrated:
1. To ensure readings from an instrument are consistent with international measurements of the same scale e.g., Mass, Temperature readings etc.
2. To determine the accuracy of the instrument.
3. To establish the reliability of the instrument i.e. that it can be trusted.
4. To determine the stability of a measuring instrument
