Why Calibration of Your Measuring Instruments is Important
                     Why Calibration of Your Measuring Instruments 
is Important
What is calibration?
Calibration is the process of 
comparing a known measurement 
(the standard) to the measurement 
made with your instrument. 
Typically, the standard's accuracy 
should be ten times that of the 
measuring device being tested. Most 
standards organizations, however, 
consider a 3:1 accuracy ratio to be 
acceptable. Sure Controls offers 
preventative field service to help you 
ensure the accuracy of your 
instruments and controls.
Calibration of your measuring instruments serves two 
purposes: it determines the accuracy of the instrument and 
the traceability of the measurement. Calibration in practice 
also includes repairing the device if it is out of calibration. 
The calibration expert provides a report that shows the error 
in measurements with the measuring device before and 
after calibration.
We can use an external micrometer as an example to 
demonstrate how calibration & measurement is done. The 
accuracy of the scale is the primary parameter for 
calibration in this case. Furthermore, these instruments are 
calibrated for zero error in the fully closed position, as well 
as for the flatness and parallelism of the measuring 
surfaces. A calibrated slip gauge is used to calibrate the 
scale. The flatness and parallelism are checked using a 
calibrated optical flat.
Why calibration is important?
All measuring devices lose accuracy over 
time. This is usually due to normal wear 
and tear. Changes in accuracy can, 
however, be caused by electric or 
mechanical shock, as well as a hazardous 
manufacturing environment (e.x., oils, 
metal chips etc.). Depending on the type 
of instrument and the environment in 
which it is used, it may degrade quickly or 
gradually. The bottom line is that 
calibration improves measuring device 
accuracy. Product quality is improved by 
using accurate measuring devices.
When should you calibrate your 
measuring device?
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 of using an uncalibrated 
measuring device could be far greater than the cost of 
calibration. As a result, it is recommended that measuring 
instruments be calibrated on a regular basis by a 
reputable company to ensure that measurement errors 
are within acceptable limits.
