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 a voltage is pretty easy: just place your multimeter’s probes across the relevant pins and read the value. Probing currents is a bit trickier, since you need to open up the circuit and place ...

I'm having problem with a starter motor on a riding mower, and need to check if the motor is getting juice and not working or if something else isn't working and no juice is getting to the starter.

A common data logging application is measuring voltage or current flowing into or out of a piece of equipment, such as a user monitoring current in solar cells, inverters, or storage batteries. These ...

One application that uses a precision power supply and DMM involves characterizing the current drawn by a device or circuit board at different voltage levels. Figure 1 shows a typical setup. Engineers ...

Measuring live voltages and current in today’s high-energy environments can result in a severe hazard to equipment and users if proper precautions are not applied. Given the risk of transients, surges ...
