Pressure differences at the test object are measured within a tight tolerance of only 1 mbar (millibar). However, the system operating pressure can be as high as 10 bar. Via an electronic pressure controller it can be preselected in 10 mbar steps with an tolerance of 2 mbar only. The system also supplies vacuum down to –1 Bar. The test sequences are generated and edited on a separate PC which displays the measurements results, too. The test applications are programmed using the popular graphics-based NI LabView software package. The GUI (graphic user interface) for the operators can be individually designed depending on customer demands, as well as the representation of the test and measurement results. The first application at a customer site is the test of an ABS (break) module under the simulated conditions as they are present in the real vehicle. During this test the pressure differences and the tightness under all operating conditions are verified, as well as the entire ABS program in a simulation run, and also a leakage measurement of the product is provided. The new test and measurement system is aimed at the exact verification of miscellaneous time-critical parameters, time-critical test cycles, tests of time-critical electronic board assemblies and of diverse objects which have to be examined using different liquids, as, for example, water, oil, etc.
