A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition under load — even below 1 V.

This is a simple and easy designed circuit which is used to test the continuity. We know that continuity tester will used to test whether there is continuity or connection between two components. Here ...

A continuity tester, as found on most multimeters today, is a great tool for finding broken connections and short circuits. But once you’ve found a short, it’s up to you to figure out which part of ...

Is the battery empty, or is there something wrong with the device? That’s always a difficult question when your walkman or some other battery-powered device appears to be dead when you switch it on.

For testing PCBs, test engineers have a variety of options ranging from venerable in-circuit testers and flying probers to functional testers and the latest in embedded-instrument technology.

Many tools can be used either for good or for evil — it just depends on the person flipping the switch. (And their current level of mischievousness.) We’re giving [Callan] the benefit of the doubt ...

According to Keysight, its i3070 Series 7 In-Circuit Test systems delivers the shortest signal path between measurement circuitry and devices under test. Keysight's family of i3070 Series 7 In-Circuit ...

Wherever circuits need protection against current overloads or short circuits, you’ll find circuit breakers. They range from fingernail-sized devices for semiconductor protection to truck-sized ...
