General Introduction

GDZC transformer winding resistance tester/winding resistance tester uses constant current source to measure the DC resistance of inductance circuit such as power transformer coil , current transformer coil and so on. GDZC  transformer winding resistance tester/winding resistance tester  has functions of self test, data processing, discharge rapidly, result print and so on.

Functions of GDZC Transformer Winding Resistance Tester/Winding Resistance Tester   

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

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

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

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

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

♦  Large-screen LCD makes operation easy.
