I.Application:
      1.GDZC Series winding resistance tester are applied to measure the DC resistance of inductance circuit such as power transformer coil, current transformer coil and so on.
      2.Also the tester could be applied to measure the cable resistance in 4-wire mode.

II.Functions:
1. Winding resistance measurement
2. Discharge the energy automatically when test is ended
3. Print the test results by micro printer
