Need powerful current source for dynamic resistance measurement?

One of the methods to assess the condition of arcing contacts is to inject high direct current (DC) through the circuit breaker contacts and measure the voltage drop during the breaker operation – a process called Dynamic Resistance Measurement (DRM). DV Power RMO micro ohmmeters can be used as a DC current source for this type of measurement. RMO micro-ohmmeter is a portable and lightweight, but powerful device, since it is able to generate up to 800 A.
