When performing electrical safety tests on the production line, manufacturers often find themselves between a rock and a hard place: minimizing production costs while maintaining throughput and increasing efficiency. While safety testing is an integral part of the manufacturing and production process, it can seem a burden when performed manually using handheld probes. Yet with advances in the industry, even the most basic testers provide test operators with other more efficient ways to test. Hipot tester manufacturers have said goodbye to the older transformer-in-a-box design, giving way to smarter testers capable of performing fully automated test sequences. While some high-end testers can be connected to a PC, the majority of modern safety testing equipment still affords operators some level of basic automation. A common offering is the addition of a set of internal input relay contacts, usually accessible via a standard DB-style connector. These contacts can be used to send signals to the microprocessor-controlled “brain” of the tester
