The CT20 is a two-part system consisting of a master continuity tester/transmitter and a two lead, bi-color (red/green) LED remote probe. The continuity tester/transmitter is used for local continuity ...

This simple but clever continuity tester sports two LEDs: RED LED = circuit resistance is < approx 10K, GREEN LED = circuit resistance <10Ω. It consumes approx 8mA from a 9V battery. When not ...

From Leatherman multitools to oscilloscopes with built-in signal generators and protocol analyzers, there seems no end to tools with multiple personalities. Everybody loves multitaskers because they ...

The circuit was developed to produce a continuity tester with a low resistance mainly for checking the connections between soldered joints. Operational Amplifier (Op-Amp) – a DC coupled high gain ...

The Arduwire UNO is an innovative shield designed for the Arduino UNO development board. This shield enables users to perform a variety of tests on cables and harnesses, including continuity, open ...

I WAS REMINDED RECENTLY of a tester I designed years ago. At the time, I wanted to build “The Ultimate Continuity Tester,” and I established a wish list of all the features I required: • A “real ...

Some kind of continuity beeper has been a standard piece of gear since the dawn of electronics. Sure, you probably have an ohm meter, but sometimes you don’t care about the actual resistance. You just ...
