An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current. Micro-ohmmeters (microhmmeter or microohmmeter) make low resistance measurements.Megaohmmeters (aka megaohmmeter or in the case of a trademarked device Megger) measure large values of resistance.The unit of measurement for resistance is ohms (Ï).The first ohmmeters were based on a type of meter movement known as a 'ratiometer'. These were similar to the galvanometer type movement encountered in later instruments, but instead of hairsprings to supply a restoring force they used conducting 'ligaments' instead.he unit of measurement for resistance is ohms (Ï).
