Software and Analysis<br>Catch the Leak Testing Drift
Regularly scheduled calibration can improve overall accuracy, but drift correction can improve real-time accuracy.
Measurement equipment needs calibration. That goes without saying. But, when it comes to leak testing equipment, there are two issues to consider regarding regular calibration. One is the calibration of the leak orifice and the second is the calibration of the instrument to the test part and process.
The periodic calibration of the leak orifice is usually performed semiannually or annually, based on companies' ISO standards. This calibration should be performed on a regular basis to assure the accuracy of the leak standard.
