1.1General 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.
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.
