1.1General introduction
APZC 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.
