The KDZR-10A transformer DC resistance tester is a high-precision replacement product for DC single and double arm bridges. The power technology used has the characteristics of small size, light weight, large output current, wide range, digital display, and internal lithium battery power supply. The whole machine is controlled by a microcontroller, which automatically completes self checking, data processing, display and other functions, and has automatic discharge and discharge indication functions. The instrument has high testing accuracy, easy operation, and can achieve rapid measurement of direct resistance.

The KDZR-10A transformer DC resistance tester adopts switch mode power supply technology, which displays the measurement results on a four and a half digit LCD screen, showing the ambient temperature or test current value. It overcomes the disadvantage of other similar products that are inconvenient to read under sunlight due to LED display values, and also has automatic arc extinguishing function.

1. The instrument has a high output current, is lightweight, and is easy to carry.
2. The power technology used has multiple current levels, a wide measurement range, and can automatically select the test power according to the load.
3. Equipped with a comprehensive protection circuit, the performance is more reliable.
4. It has a discharge sound alarm, clear discharge indication, and reduces misoperation.
5. Fast response speed, stable measurement data, and automatic data refresh during testing.
6. Intelligent power management technology effectively reduces internal heating of instruments and saves energy.
7. Powered by lithium-ion batteries, convenient for on-site operation.
