If you were to ask a random Hackaday reader what their most fundamental piece of electronic test equipment was, it’s likely that they would respond with “multimeter”. If you asked them to produce it, ...

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 ...

It’s remarkable how tiny electronics have become. Heaven knows what an old-timer whose experience started with tubes must think, to go from solder tags to SMD in a lifetime is some journey. Even the ...

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 ...
