*** Note: During the course of my exploration, I actually fried my tester... I already had another one on the way, so I'll build another one. However, hopefully you do not fry yours. I'll describe what I was doing at the end of this Instructable. If you use a 9v for testing ...
Safety is paramount when it comes to testing and troubleshooting. Because the insulation resistance tester produces significant DC voltages, it can never be connected to an energized circuit. Also, the output of the tester can destroy electronic circuits. Never connect an insulation resistance tester ...
Integrated circuitTesting: Integrated Circuit(IC)It is one of the most critical components in modern electronic devices. The testing of the IC includes functional testing, DC parameter testing, AC parameter testing, and timing testing to ensure that the IC can operate normally under various working ...

, or voltage meter, it measures the difference in electrical potential between two nodes of an electrical circuit. Admittedly, that sounds pretty complicated and technical. However, it takes just a few steps to master. Knowing how to use a multimeter works the same as using a voltage tester....
For many years, mainland Western Europe has used a mains electricity supply rated at nominally 220VAC 50Hz while the UK used 240VAC 50Hz. In 1994, the European Union state members decided to proceed with a voltage harmonisation at 230Vac. This meant that consumers could be sure that a produc...
Electricians use a continuity test to determine if there's a break in the circuit, so the fixture must be isolated from power to get a reading. If you have a plug-in lamp, you can just unplug it, but if you're testing a wall or ceiling fixture, you need to disconnect it from the...
