There are four DC currents to select for WRT-10A which has a large output power,the power of transformer DC winding coil resistance tester is very little. Used four lines.It is quick,stable,high precision for testing the winding resistance.
In addition, this winding coil resistance tester set has a strong ability for anti-jamming ,over current ,over voltage and discharge.the security is also very high, So it is a ideal tester for testing various resistances especially the sensibility equipment.
A new switching power supply technology makes output current more stable and power larger than before.
This winding 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 winding resistance tester 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.
