Transformer Winding Coil DC Resistance Tester Micro Ohmmeter
I. Introduction:
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.
This winding resistance meter has functions of self test, data
processing, discharge rapidly, result print and so on.
II. Functions:
A new switching power supply technology makes output current more
stable and power larger than before.
This coil resistance tester has an advanced signal process circuit which has a good performance at anti-noise. Test data is precise and stable.
The dc resistance meter has protections to prevent circuit over-current, circuit over-voltage, wrong operation, discharge and so on.
This micro ohmmeter is 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.
