LabVIEW Case Studies | Projects
Our client already had a test system in place, but the tester (really two test systems testing two different product variants) was becoming obsolete. The tester was old, hardware was failing, and it was getting harder and harder to keep it reliably running. They wanted a new tester to improve reliability, but maintain the functionality of the existing tester to keep the FDA-mandated verification and validation time to a minimum.
The updated end-of-line manufacturing test system maintains the functionality of the old test systems, but with updated hardware and software. The same software is utilized for both the manual test system update and the automated test system update. Our client deployed 6 manual testers and 1 automated tester.
- Improved maintainability and reliability with updated hardware and software
- Maintains existing test system functionality to keep certification time down
There were two variants of the new test system. One was for an older product line that utilized manual test, with an operator that connected/disconnected the UUT, and initiated the test. The other was an automated tester, integrated into a manufacturing machine. Both testers utilized custom fixtures (provided by the client), off-the-shelf NI measurement hardware (selected by Viewpoint), and custom test software (developed by Viewpoint). The software is configurable for both the manual test system and the automated test system.
