RMO-TH is a handheld, battery operated, fully automatic test set specially designed for winding resistance measurements of transformers and other inductive objects, such as motors and generators. It can also perform demagnetization of transformers, motors, and generators.
Winding resistance is determined by injecting DC current through a winding, accurately measuring DC voltage across the winding, and then calculating resistance as the ratio of voltage and current.
The device generates true DC ripple-free currents. Both the injection of the current and the discharge of energy from transformer magnetic circuit are automatically regulated.

Standard set: Handheld Winding Ohmmeter RMO-TH, Windows-based DV-TR PC software, power supply adapter, transport bag, carrying belts.
