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, ...

Brushless motors have a lot of advantages over traditional brushed motors. However, testing them can be a bit of a pain. Because the resistance of the motor’s coils is usually very low, a standard ...

The AC71 is a clamp-style digital multimeter (DMM). The DMM's AutoTectâ„¢ feature automatically senses what type of measurement is being made when test leads are placed across a measurement point.

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 ...

Most precision digital multimeters (DMMs) and many source measurement units (SMUs) offer both two-wire and four-wire resistance measurement capabilities. However, these two techniques are not equally ...
