DC Resistance Tester

Type: ZC-205B
The DC resistance of transformer 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 . In order to meet the needs of rapid measurement of transformer DC resistance, our company developed ZC-205B DC resistance tester by using our own technical advantages .
ZC-205B DC Resistance Tester adopting new power technology, it has the characteristics of small size, light weight, large output current, etc. The device is controlled by single chip microcontroller, which can automatically complete the functions of self-check, data processing, display and so on. It has the function of automatic discharge and discharge indication.The instrument has the advantages of high precision and easy operation, which can realize the rapid measurement of transformer direct resistance .
