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 ...

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 ...

Understand and comply with relevant codes and standards such as NFPA 70B, NFPA 79, and NEC 110.7 to ensure proper insulation testing procedures. Develop a comprehensive job safety plan that includes ...

Electrical safety testers—often referred to as “hipot” testers—are an integral part of electrical and electronic equipment manufacturing. Hipot testers get their name from the high-potential (high ...
