Portable DC Winding Resistance Tester is an innovative product with compact size, hand-held operation, more portable and easy to carry.

The product is not only suitable for the measurement of transformer, transformer, reactor and other inductive test products, but also suitable for the measurement of copper bars, conductors, switch contacts and other resistive test products. The instrument has fast testing speed and high accuracy

Functional Characteristics

1. Adaptive lithium batteries or 220 v ac supply. After a single charge, the dc resistance of hundreds of transformers can be tested continuously. The test process is simple and convenient

2.The output current is six grades, the maximum output current is 10A, the maximum output voltage is 25V, and the current can be automatically selected, which is convenient and fast.
3.Wide range and high accuracy,500uΩ~50KΩ.

4. It has the function of resistance temperature conversion, and can be equipped with wireless temperature measurement module, which can measure the field test temperature in real time to ensure the accuracy of resistance commutation value.

5. It has many kinds of protection functions, such as back EMF protection, broken line protection, power-off protection and over heating alarm.

6. 5.6-inch super industrial high-brightness color LCD screen, still visible under strong sunlight.

7. equipped with external printer, facilitate data printing

8. It can be stored locally and on USB memory.
