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, ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...

This multimeter add-on is called the Half Ohm. It allows you to measure small resistance values, and can be used to track down shorts on a PCB. The board acts as a pass-through for both probes. When ...

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 ...

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 ...

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 ...
