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 ...

When you pull out that multimeter to measure resistance, you might give some thought as to whether you should use the meter’s two-wire or four-wire probably–if it even has a four-wire option. But you ...

Because they are integral to a variety of common test applications, ensuring of high-Ω measurement accuracy can be critical High-resistance measurements are integral to a variety of test applications, ...

While ac internal resistance (ACIR) measurements are quite common and somewhat standardized when measuring lithium-ion cells, dc internal resistance (DCIR) measurements are nonstandard and generally ...

The DMM is arguably the most versatile electrical test instrument we have. Even the most basic model can measure voltage, current, and resistance. You can use the resistance measurement function for ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

This is a scratch-build meter for measuring the internal resistance of Lithium Polymer cells. [Bleuer Csaba] uses the LiPo cells for RC vehicles and thet take quite a beating from the motors they’re ...

The majority of metal traces used to produce electrical connections in semiconductor devices begin life as blanket metal films that are later patterned and etched to create conductive connections ...

Hands down — without a doubt, one of the most universally searched topics on EC&M’s website from a historical perspective is “insulation resistance testing.” As a result, some of our most popular ...

Integrated circuit (IC) design reliability has always been important and essential to market success. After all, if no one could count on your product to operate as designed, and for as long as ...
