Fault analysis at EWPTE Show 2025

Fault analysis in electrical wire harness testing

Today’s test systems are often only used to confirm pass/fail results, with valuable data being disregarded.

In May 2025, we delivered a tech talk on fault analysis at the EWPTE show in Milwaukee. Catch up on the talk here for practical advice on how to store and analyse test data to improve efficiency, reliability, and future readiness.
