ZXR-50A DC resistance tester adopts the new power technology. It has the characteristics of small volume, light weight, large output current, good repeatability, strong anti-interference ability, perfect protection function and so on. The whole machine is controlled by high speed single chip microcomputer, and has high automation level. It has the function of automatic discharge and discharge alarm. The instrument has high precision and easy operation, and can be used to measure the direct resistance of the transformer.
1. The whole machine is controlled by high-speed single-chip microcomputer, high degree of automation, easy to operate.
2. The instrument uses a new power technology, current stalls and more, measuring range, suitable for large and medium-sized transformer DC resistance measurement.
3. Perfect protection function, which can reliably protect the instrument against the back-EMF. The performance is more reliable.
