In the second part of this series on the highs and lows of resistance measurements, I illustrated the differences between two-wire and four-wire resistance measurements on an actual low ohmic sample ...

Resistance standards are incredibly useful, but like so many precision references they require regular calibration, ...

Megger now offers a digital low resistance ohmmeter that can deliver reliable results when using long test leads. The DLRO2, a 2 Amp handheld tester, is ideal for use in production line testing and ...

The types of insulation used in rotating machines have continued to evolve and precipitate changes to insulation resistance testing since 1974 when IEEE Std. 43, Recommended Practice for Testing ...

Insulation resistance testing is one of the most useful predictive maintenance tests available. This test gives insight into the integrity of insulation. The higher the resistance across the ...

All conductors show some opposition to electric current. This opposition to current is called resistance. A good conductor has low resistance. A poor conductor, or insulator, has high resistance. The ...

In the first part of this series on the highs and lows of resistance measurements, I discussed the basic principles for making two- and 4-wire resistance measurements for measuring resistances of less ...
