About Resistance Meters

Generally the ohmmeter family is divided into two distinct types. Micro-ohmmeters (also known as microhmmeter) are capable of making low resistance measurements, but can’t be used to measure larger values of resistance like you may find on high voltage equipment. The other form, the megohmmeter, can measure incredibly large levels of resistance and is a great solution for those working with higher levels of resistances.
