All CETA test devices are calibrated with calibration standards before delivery and after maintenance. The used calibration standards are controlled regularly. A certificate of the test device documents the calibration, that should be repeated in regular intervals. These time intervals depend on the operating conditions and on the company-interval regulations of the test equipment control department.

By means of calibration masters (standard leak and master jets) the proper function of the test device including the fixture can be tested (e.g. by shift changeover).

 
The calibration masters are individually dimensioned for the application specified by the pressure and flow rate. Before delivery each calibration master is calibrated.

Standard leaks are used in leak detection applications.

Master jets have larger flow rates than standard leaks and used in flow testing applications.
