Micro-ohmmeters (microhmmeter or microohmmeter) make low resistance measurements. Megohmmeters (also a trademarked device Megger) measure large values of resistance. The unit of measurement for resistance is ohms (O). The first ohmmeters were based on a type of meter movement known as a 'ratiometer'.visit us at https://goo.gl/EU2dc5 to know more
