GDZC- Series Transformer DC Winding Coil Resistance Meter It is applied to measure the DC resistance of inductance circuit such as power transformer coil,current transformer coil and so on. Also the tester could be applied to measure the cable resistance in 4-wire mode GDZC Series 1A to 50A Transformer Winding Resistance Meter uses Constant current source to measure the DC resistance of inductance circuit such as power transformer coil, current transformer coil and so on. GDZC Series 1A to 50A Transformer Winding Resistance Meter has functions of self test, data processing, discharge rapidly, result print and so on. Functions 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.
