The units feature 6 decades with non-inductive, precision resistors mounted in a low-noise, shielded housing. After inheriting the DB62 series from esi, IET used its own resistance tech - nology to significantly improve the stability of the unit. Features:

  • Four available models
  • High accuracy: ±(0.01% + 2 mΩ)
  • Serves DC through audio frequency
