Measuring rise time for a power source. Voltage vs. time signals measurements via a scope. A practical setup for battery testing. I was recently asked a question about a dc power supply, aka a voltage ...

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 ...

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 power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

In this DIY electronics project, I’ll show you how I built a working non-contact voltage tester from scratch! Perfect for beginners and hobbyists, this simple tool helps detect live wires safely no ...

The Cordless Digital Phasing Tester allows linemen to test for phase sequence and angles, voltage ranges between 4 kV and 69 kV and operates at a range of up to 100 ft.

If a poll was taken to determine what aspect of the hot rod hobby enthusiasts dislike the most, there’s a high likelihood that “diagnosing electrical issues/gremlins” would be the popular answer. An ...

Klein Tools introduces the Non-Contact Voltage Tester with Laser Distance Meter (Cat. No. NCVT-6), which detects the presence of AC voltage and measures distances up to 66 ft – all in one lightweight, ...
