Ⅳ: Functional Characteristics About The dc resistance test set:
1. Max 24V output voltage which makes it convenient to choose a larger test current when the resistance value is high, and improve the test speed.
2. 7 inch high resolution LCD touchscreen, easy on-site operation. Good visibility even under strong light.
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
