While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...

For the past couple of days 2 of the UPS'es in my house have been clicking like there is a line sag. The UPS'es are on completely different circuits in the house, but both are pretty basic "Connext" ...

If a product uses power, then power consumption and power quality measurements must be made as part of product design and test. These measurements are essential to optimize product design, comply with ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

Designed for ESD testing, the 149-03 and -04 digital high-voltage meters can measure up to 40 and 60 kV, respectively, and feature an input impedance of 100 GW. The portable instruments operate from ...
