Main features for the winding resistance tester
1. Equipped with high speed single chip, ensure a high degree of automation.
2. Ecrã tátil LCD de 7 polegadas de alta resolução, fácil de utilizar no local. Boa visibilidade mesmo sob luz forte.
3. New power supply technology with multiple current gears and a wide measurement range. The current can be automatically selected according to the load, which is suitable for DC resistance measurement of small and medium-sized transformers and voltage transformers.
4. Multiple protection functions such as back-EMF impact, interruption of the test process, power failure, power supply overheating, etc., which can reliably protect the instrument from back-EMF impact, and simultaneously sound an alarm.
5. With any temperature conversion function of copper and aluminum materials, touch input of any winding temperature and converted temperature
6. Internal data storage up to 1000 sets.
7. Bluetooth, RS232 port and USB Port for data storage and PC communication
8. Built-in high-speed micro printer
9. See our Testador de resistência DC for more information
