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:

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.
