Transformer Winding Resistance Tester

1.1General introduction

GDZC Series

Transformer Winding Resistance Tester uses Constant current source to measure the  Winding resistance of inductance circuit such as power transformer coil , current transformer coil and so on. The tester has functions of self test, data processing, discharge rapidly, result print and so on.

1.2Functions

1 A new switching power supply technology makes output current more stable and power larger than before.

2 The tester has an advanced signal process circuit which has a good performance at anti-noise. Test data is precise and stable.

3 The tester has protections to prevent circuit over-current, circuit over-voltage, wrong operation, discharge and so on.

4 Small size, light weight and more suitable for outdoor using.

5 Varies levels of output current make measuring range more wide.

6 Large-screen LCD makes operation easy.
