This simple micro ampere meter circuit can help in measuring small currents in five ranges: from 1 µA to 10 mA. The meter is working in this way: the current being measured Ix shifts the input voltage ...

Electricity meter sticks on circuit breakers Berkeley Lab researchers have developed a peel-and-stick electricity meter which allows individual circuits in the home and industry to be accurately ...

This article will discuss the smart meter, current sense design, and components necessary for circuit protection in a smart meter and various communications environments.

MORRISTOWN, NJ — Want to improve your hvacr circuit troubleshooting accuracy? Make sure that the ammeters you use are appropriate for today’s electrical loads, many of which have electronic signals ...

The portable meter can also be used to make low-value, non-inductive resistor (DCR) measurements. The tester can detect a shorted capacitor in its DCR cycle and also determine its ESR value to ...

The meter beeps when it detects a closed circuit, so there’s no need to look at the meter while testing. The resistance required to trigger the beeper varies from model to model of DMM.
