Why calibration is important and needed?

1. Is requirement of your Quality System.
2. Is about accuracy of all measuring devices.
3. Equipment accuracy will degrade over time. 
4. Typically caused by normal wear and tear. However, changes in accuracy can also be caused by electric or mechanical shock or a hazardous manufacturing environment (e.x., oils, metal chips etc.). 
5. Depending on the type of instrument and the environment in which it is being used, it may degrade very quickly or over a long period of time. 
6. The improtant mindful of calibration is that it's improves the accuracy of the measuring device. Accurate measuring devices improve product quality.

1. According to the recommendation of the manufacturer.
2. After any mechanical or electrical shock.
3. Periodically (annually, quarterly, monthly)
4. Requirement of your quality system.​

1. The hidden costs and risks with un-calibrated measuring device could be much higher than the cost of calibration. Therefore, it is recommended that the measuring instruments are calibrated regularly by a reputable company to ensure that errors associated with the measurements are in the acceptable range.
