Proper safety procedures are critical when testing high-voltage systems. As the following examples prove, mistakes happen. However, when the safety of you and your coworkers is at stake, neglecting ...

AVTs help reduce the risk of exposure to electrical hazards and improve worker safety by automating and simplifying the process of verifying the absence of voltage. The importance of creating a safe ...

A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition ...

Voltage tester, tick-tracer, glow-tip, non-contact voltage tester... whatever. Same thing. I call it a voltage sniffer, but the technical name for this device is a capacitive voltage sensor. That's a ...

The circuit was designed to provide a means for measuring the operating voltage of zener diodes before applying on a circuit. Zener Diode – a special kind of diode that permits the flow of current in ...

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 ...
