Transformer Winding Resistance meter/10A/20A DC Resistance tester

 I. DC Resistance tester  Introduction:

The DC resistance is the transformer’s semi-finished product, finished product test, installation, commissioning test, and electric part prevention test necessary test project,the transformer coil can effectively find the device welding, connecting parts loose, missing unit, disconnection, and other manufacturing default and other hidden danger occurred after operation.

The device is controlled by the microcontroller, with a high degree of automation, automatic discharge functions. It is a test instrument of high precision, simple, direct way to achieve fast transformer measurement.
