RMO-D series contain 3 models of powerful and lightweight micro ohmmeters:

   RMO200D – test current from 5 to 200 A, weighs only 9 kg / 20 lbs
   RMO500D – test current from 5 to 500 A, weighs only 12 kg / 26.5 lbs
   RMO600D – test current from 5 to 600 A, weighs only 12 kg / 26.5 lbs

  • Measuring range: 0,1 μΩ – 999,9 mΩ
  • Resolution: 0,1 μΩ
  • Typical accuracy: ± (0,1 % rdg + 0,1 % FS)
  • Remote Control Unit (optional)
  • Both Sides Grounded Unit (optional)
  • SINGLE / CONTIN / BSG / DTRtest modes

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.
