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 ...

This simple circuit tests speakers, microphones, transformers and voltage. It’s basically a very low frequency oscillator that produces extremely short ‘fruity’ pulses. The type of sound produced is ...

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 ...

Because of its mass, a battery takes a long time to change temperature. If a vehicle sits out all weekend in a zero-degree environment, it might take 30 hours to warm up the battery. Use the outside ...

Sometimes it is necessary to split a single power supply in two or more parts which are not necessarily equal. This is the case with 6-, 12-, 15-, 24-, 36- or 48-V power supplies from dry batteries or ...

Electrical safety testers—often referred to as “hipot” testers—are an integral part of electrical and electronic equipment manufacturing. Hipot testers get their name from the high-potential (high ...

Electrical snafus are among the most annoying problems with older cars. Unlike tires or bodywork, there's something about electrical systems that seems to baffle many car crafters. We could blame it ...

What type of equipment is best to use for low-voltage test of battery cells? What is an electronic load, and how does it work? How to overcome a major limitation with the low-voltage-discharge test.
