I work a lot with high voltages and others frequently replicate my projects, so I often get asked “What voltage is needed?”. That means I need to be able to measure high voltages. Here’s how I do it ...

Measuring extremely high dc voltages of 10 kV or more usually requires a suitably equipped high-voltage ohmmeter or a digital multimeter and high-voltage divider, along with the proper safety ...

In many applications where the input is not under system control but rather connects to the outside world, such as test equipment, instrumentation, and some sensing equipment, it is possible for input ...
