Electrical DC Resistance Meter, Coil Winding Resistance Tester

Introduction:
GDZC Series Transformer DC 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. The tester has functions of self test, data processing, discharge rapidly, result print and so on.
Functions:
V A new switching power supply technology makes output current more stable and power larger than before.
V The tester has an advanced signal process circuit which has a good performance at anti-noise. Test data is precise and stable.
V The tester has protections to prevent circuit over-current, circuit over-voltage, wrong operation, discharge and so on.
V Small size, light weight and more suitable for outdoor using.
V Varies levels of output current make measuring range more wide.
V Large-screen LCD makes operation easy.
