RMO-D series of Micro Ohmmeters (hereafter referred to as “RMO-D”) is based on a state of the art technology, using the most advanced switch mode technique available today. RMO-D generates a true DC ripple-free current with automatically regulated test ramps. During a test the RMO-D ramps with increasing current before measuring and decreasing current after the measurement. This eliminates magnetic transients.
The RMO-D 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 RMO-D 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-D 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.
The RMO-D instrument has four separate test modes:
- SINGLE mode
- CONTIN mode
- BSG mode (Both Sides Grounded)
- DTRtest mode (Dead Tank Resistance)
The DEMAGNETIZATION feature enables for full automatic demagnetization of a current transformer core after the measurement.
