Contact Resistance Test Sets for Efficient Electrical Testing
-
The RMO-H micro ohmmeters are ideal for a number of applications for contact resistance measurements of non-inductive test objects. Typical applications are testing a circuit breakers and disconnecting switches, high-current bus bar joints, cable splices, welding joints, etc. The set is equipped with the thermal and overcurrent protection. The RMO-H has a very high ability to cancel electrostatic and electro-magnetic interference in HV electric fields. This is achieved by very efficient filtration utilizing a proprietary hardware and software. Features: • Measuring range: 0,1 μΩ – 3000 mΩ • Resolution: 0,1 μΩ • Typical accuracy: ± (0,1 % rdg + 0,1 % FS) up to 1Ω range • Handheld, only 0,95 kg (2.1 lbs) weight • IP54 mechanical protection rating • Designed to make multiple measurements and full day’s work of testing without a battery recharge • Safe testing in Both Sides Grounded (BSG) conditions • 1 meter cables -
