If you’re sending your equipment in for calibration, it’s likely you know why it’s important. Calibrating your equipment can prevent injury to the persons operating the equipment or injury from bad results. When you receive a calibration report, it can sometimes be confusing. However, the information that is contained in these reports helps you to pass inspections with accrediting bodies, as well as know whether your equipment is safe to use. It is important to know why and how all this information is useful, so here’s what do with your calibration report results now that you’ve received them.
One of the most important questions of instrument calibration is, “How accurate are my instruments measurements?” By analyzing the results on a calibration report, this question can be answered.
As previously mentioned, calibration results given on the calibration report may vary both in specific values and also in formats, but usually display the value of a standard and the results obtained when using the instrument to measure that standard. The calibration report will also display the calculation of the actual error of the instrument calibration and the correction value.
These results help display and maintain instrument accuracy and can be used for repair purposes or readjustment.
When using an instrument, it is important to ensure that the readings can be trusted. Unfortunately not all measurements will read perfectly; therefore, knowing that your instrument is reliable after calibration is crucial. A calibration report displays instrument reliability.
The results on the calibration report indicate the degree of accuracy of an instrument. A calibration report includes a measurement uncertainty ratio which helps to indicate if an instrument is drifting. If an instrument’s measurements are reading outside of the calibration reports given ratio, than the instrument has drifted out of calibration is not reliable.
Calibration report results are most useful if they can be related to other measurements. Traceability helps companies to maintain manufacturing tolerances, which in turn helps companies trace their measurement to a specific standard.
Traceability is particularly important to ensure overall accuracy and reliability and aids in inspections.
Taking uncertainty into account helps to determine the accuracy of instrument measurements. A calibration report can be used to determine if an instrument is reliable and accurate by comparing instrument measurements to the uncertainty measurement ratio calculated on the report.
In conclusion, calibration report results can be used to determine the overall accuracy and reliability of an instrument and can also be used to help determine when an instrument needs to be recalibrated.
