The RMO series of micro ohmmeters are designed for the contact resistance measurement of non-inductive test objects. The RMO Series of instruments are based on state of the art technology, using the most advanced switch mode techniques available today. The RMO Series generate a true (ripple free) DC current with automatically regulated test ramps. During the test the RMO Seriesramps with increasing current before measuring and decreasing current after the measurement. This approach significantly reduces magnetic transients.

With over 18 Years in designing and manufacturing micro ohmmeters, DV Power has established wide range with 16 portable and 3 handheld models of high-precision micro ohmmeters.

Applications

  • Power circuit breakers (including dead-tank circuit breakers)
  • Disconnecting switches
  • Interrupters
  • Cable splices
  • Welded joints
  • Groundings
  • Bar installation

A range of 6 powerful and lightweight micro ohmmeters with current ranges up to 600 A. With single, continuous and dead tank resistance test modes the RMO-A Series are highly cost-effective micro ohmmeters.

A range of 7 powerful and lightweight micro ohmmeters with current ranges up to 800 A. For added user safety a Both-Sides-Grounded measurement mode is available alongside single, continuous and dead tank resistance test modes.

A range of 3 powerful and lightweight micro ohmmeters with current ranges up to 600 A. For added user safety a Both-Sides-Grounded measurement mode is available alongside single, continuous and dead tank resistance test modes. To decrease testing time the RMO-D series have an automatic demagnetisation feature.

A range of 3 powerful handheld battery-operated micro ohmmeters with current ranges up to 300 A. For added user safety a Both-Sides-Grounded measurement mode is available. Unlike other handheld micro ohmmeters the RMO Series offers a user selectable test current and produces a constant ripple-free current during
