Today, there’s a party at your home. And you are busy detecting faults in the decorative lights hanging over the boundaries of your house. You want to finish the job before evening. But daylight adds ...

The continuity tester is a handy adjunct to an ohmmeter. The unit or component whose continuity is to be checked is connected between terminals E1 and E2 (which may be probes or croc clips). The test ...

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 ...

If sometimes you are absent-minded like me, this continuity tester will forgive you by protecting itself and the circuits under test. Withstands sustained voltages up to 35V. Safe open circuit voltage ...

The OhmGuard Hose Continuity Tester by Newson Gale is a device designed to ensure that a string of assembled hoses have good electrical continuity with a grounded truck. Good continuity with the ...

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 ...

A simple standalone continuity tester, based on the ultra-inexpensive (~$0.03) Padauk microcontroller and a piezo buzzer. Turns on a Piezo Buzzer when there is continuity detected between the Probe ...

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 ...
