The high-power generation of 100A and 200A micro-ohmmeters is based on compact technology that allows significant weight and size reduction of the ohmmeter to less than 11 kg. The housing is extremely durable and designed to protect against all challenges of daily use. Internal thermal sensors monitor all sensitive components and thus ensure that the microohmmeter is not damaged. Robust ohmmeters of this type are used for resistance measurements on motors, transformers, circuit breakers, breaker contacts, cables, switches and contactors. The micro-ohmmeters are supplied with all accessories, including the big 4-wire Kelvin connections, which means that any interference by lead and contact resistances can be prevented. The ohmmeter MPK-203 and MPK-204 are also equipped with an internal memory and a RS232 port. With the ST ® Meter software, the results can comfortably be read and processed.
