Mikroohmmeter DV Power RMO300A

Ideal for contact resistance measurement of circuit breakers, disconnector swithes, bus-bars, etc. RMO300A Micro Ohmmeters (hereafter referred to as “RMO300A”) is based on a state of the art technology, using the most advanced switch mode technique available today. RMO300A generates a true DC ripple-free current with automatically regulated test ramps. During a test the RMO300A ramps with increasing current before measuring and decreasing current after the measurement. This eliminates magnetic transients. The RMO300A instrument can store internally up to 500 measurements. All measurements are time and date stamped. Using the DV-Win software a test can be performed from a user’s PC, and the results can be obtained directly on the PC. Communication between the RMO300A and a PC is through an USB (as standard) or an RS232 cable (as an option). Bluetooth communication interface is also available as an option. Using the DV-Win the result can be arranged as an Excel spread-sheet which can be later shown as a diagram and printed for a report. The set is equipped with a thermal and an overcurrent protection. The RMO-A has a very high ability to cancel electrostatic and electro-magnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing a proprietary hardware and software.
