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.
