Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...

Isabellenhütte has developed the Micro-Ohm-Meter IMR-B-R020 for applications in research, development and labs as well as in manufacturing and industrial applications. The Micro-Ohm-Meter is deployed ...

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...

When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of a ...

Lightning protection is a critical aspect of establishments that operate sensitive electrical equipment, especially in the broadcast industry. Tied to this first line of protection against lightning ...

Interpreting a data sheet for a static-control product requires a certain level of knowledge and experience. Often, you must wade through myriad specifications, test methods, and claims without fully ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

Usuallyyour meter will be bought or adapted for a specific measurement and youwill not have to make special efforts to get it to read what you want.Or your schematic will specify the sensitivity of ...

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, ...
