Low-Resistance Ohmmeters are highly accurate, easy to operate instruments measure resistance with resolution as fine as 0.1 micro-ohm. Digital micro-ohmmeters and DLROs measure contact resistance of switch and circuit breakers, aircraft frame bonds, and rail and pipeline bonds just to name a few of the applications. Test currents range from 0.5 mA to 100 amps covering a multitude of applications that require precise low-resistance measurements. Using a Low-Resistance Ohmmeter is imperative as there are many factors that can cause issues that require resistance testing. General wear and tear, corrosion, extremes in temperature and even excess vibrations can cause damage to the electric components. This can lead to poor grounding, overheating of appliances, excessive levels of power loss, the malfunctioning of circuit breakers, and other protective components.
