Abstract
A test device including two measuring systems is provided. The test device includes a first measuring system which is configured for leakage testing of a test object, and a second measuring system which is configured for dimensional checking of the test object. The first measuring system has at least one connecting region, by which a test medium can be introduced into the test object. The test object can be set into rotation via the at least one connection region, on which the dimensional checking is based.
Claims14
A test device, comprising:
- a first measurement system that is configured for a leak tightness test of a unit under test;
- and
- a second measurement system that is configured for a dimensional check of the unit under test, wherein
- the first measurement system includes at least one connector region via which a test medium is introducible into the unit under test and which is provided for receiving or holding the unit under test,
- the unit under test is settable, via the at least one connector region, into a rotation on which the dimensional check is based, and
- the at least one connector region is mounted so as to be centered on and turnable about a turning axis.
