Transformer DC Resistance Tester also named Transformer Winding Resistance Tester, It is a necessary testing project for transformer transition, overhauling and changing tap switch, it is also an important detecting project after fault. Transformer DC Resistance Tester is a quick test equipment for testing transformers, generators, motors, lines and other DC resistance.
Overview
1. Large output current wide measuring range small size light weight simple operation;
2.Fast test speed，high measurement accuracy，good retest capacity，strong anti-interference capability；
3. With perfect function of protection circuit and discharge alarm reduce the wrong operation good reliability;
4. Adopting high speed micro-controller to automatically complete the judgment of steady flow data acquisition and processing and display resistance;
5. Using 192 * 64 large-screen LCD display outdoor display is clearly visible;
6. Built-in high-capacity a non-volatile memory can store 500 sets of measurement data;
7. Built-in high-precision real-time clock function date and time can be calibrated.
8. With high-speed micro thermal printer: can print measurement and historical data.
