Operating mode CTRL – calibration (step-by-step) Purpose: The operation mode CTRL (Control / regulation) is selected for the calibration of a test device in individual steps. In case the calibration takes place at the same pressure ranges frequently, we recommend the operation mode AUTO.

Operation manual Pneumator ∙ Testo Industrial Services ∙ Version 1.4 ∙ 2019 ∙ Page 10 Leakage test (LEAK) In case the test device has to be checked whether it is connected pressure-tight, you can start a leakage test with the LEAK button at each pressure step, upon reaching a stabilized value.
Operation manual Pneumator ∙ Testo Industrial Services ∙ Version 1.4 ∙ 2019 ∙ Page 11 7. Operating mode AUTO – calibration (programmed steps) Purpose: The operation mode AUTO (automatic regulation) is chosen for the calibration of test devices in preprogrammed steps. This makes sense and is timesaving if several test devices have to be calibrated with the same pressure sequences.
