Instructables user [Rudolf] wrote in to share a handy little tool he created with ham radio operators in mind. Now and again, he found himself connecting to an unknown power supply, and rather than ...

This Design Idea describes a handy continuity tester with two modes of operation: It may sound if it detects continuity between its two probes, or it may sound when it detects no continuity. The ...

Hastings new voltage tester ensures safety for line workers by giving them the voltage information they need to make the right decisions on the job. This live tester, non-contact voltage detector uses ...

For product safety testing, the basic instrument for many years has been the dielectric voltage withstand or high-potential (hipot) tester. But like so many other instruments that must deal with today ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...
