As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

All too often, scientists and engineers tend to take the process of measuring resistance for granted. All it takes is attaching test leads to a digital multimeter (DMM), setting its function to ...

Maintenance professionals are constantly being deluged with new models, new manufacturers, and new functionality in handheld digital multimeters. Safety features are perhaps the most critical factors ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

Have you ever needed to hunt down a short circuit, but you’ve had no idea where it is or how it’s happening? As it turns out, there are tools to help in that regard. Enter the Leakseeker-89R. The ...
