20A Transformer Winding Ohmmeter
Model: TWO-120S
Maximum 20A current for measuring winding resistance of power transformer
Transformer Winding Ohmmeter is designed to measure the dc resistance of all types of magnetic windings accurately. It can test transformers and rotating machine windings and perform low-current resistance measurement on connections, contacts and control circuits. TWO-120S can be operated easily via 7-inch high brightness touch screen.
