What is calibration?
Calibration is a comparison between a known measurement (the standard) and the measurement using your instrument. Typically, the accuracy of the standard should be ten times the accuracy of the measuring device being tested. However, an accuracy ratio of 3:1 is acceptable by most standards organizations.
Calibration of your measuring instruments has two objectives: it checks the accuracy of the instrument and it determines the traceability of the measurement. In practice, calibration also includes repair of the device if it is out of calibration. A report is provided by the calibration expert, which shows the error in measurements with the measuring device before and after the calibration.
A measuring device should be calibrated:
According to the recommendation of the manufacturer.
After any mechanical or electrical shock.
Periodically (annually, quarterly, monthly)
The hidden costs and risks associated with un-calibrated measuring device could be much higher than the cost of calibration. Therefore, our comapny can issue the factory calibration report to ensure that errors associated with the measurements are in the acceptable range.
