Transformer Ohmmeter, also called transformer resistance tester. It is mainly used to test transformer winding resistance. TO712B Transformer Ohmmeter is mainly applied for factory test in transformer manufacture, verifying the factory test reading, or finding out the presence of the defect in on-site transformer. To test transformer winding resistance can effectively find the defect as follow: Ø Short circuit, open circuit, wrong wire connection in electric circuit Ø Welding defect of winding wire, between winding and leads Ø Whether tap switch, leads and the casing keep good contact Ø Whether coil specification meet the requirement of design The instrument adopts new constant-current technology, with the advantages of constant output, low loss, greatly improve the measure precision. The tester for high testing precision, simple operation, can realize the rapid and reliable measurement of transformer winding resistance.
