Test modes and typical applications
| Test mode | Typical application |
| Pressure decay | Leak tightness of test parts |
| Pressure rise | Leak tightness of combined chambers |
| Dynamic pressure | Continuity test |
| Pressure steps | Opening point of valves |
| Closed component | Leak tightness of sealed test parts |
| Volume measurement | Determination of test part volumes |
| Mass flow | Leak tightness of test parts with large volume and small rates |
| Flow | Flow though pipes |
Overview test data and test ranges

Typical applications
- Testing for oil-tightness or watertightness
- Leak testing according the requirements of the IP protection classes
- Testing of enclosures (e.g. gear box cover, reservoires, shiners)
- Testing of coolers, gear boxes (inner and outer leak tightness)
- Leak testing of parts with venting elements (e.g. membranes)
- Testing of sensors, clocks, micro electronic devices (closed components)
- Testing of elements with hydraulics (e.g. shock absorbers, servo pumps)
- Continuity test of pipes and valves
- Determination of the opening and closing point of valves
- Flow test of pipes, valves, membranes, exhaust-gas sysytems
