Transformer Winding Resistance Tester with Battery
Short Description:
ITEM: RUN-DCR10A
Built-in battery, easy for on-site test.
Used for checking the welding quality of the winding joints and whether the windings have inter-turn short circuits, check whether the contact of each position of the voltage tap switch is in good condition, whether the actual position of the tap changer matches the indicated position, whether the lead wire is broken, and the multi-stranded wire is wound in parallel. Whether there is stock breakage, etc.
SERVICE: The instrument will be repaired and replaced free of charge for product quality problems within one year from the date of purchase, and will provide lifetime warranty and
technical services. If you find any abnormalities or malfunctions in the instrument, please contact the company in time to arrange the most convenient solution for you.
Ⅰ: Overview about the Transformer winding resistance meter with battery:
The Transformer Winding Resistance Meter adopts a brand-new power supply technology, which has the characteristics of small size, light weight, large output current, good repeatability, strong anti-interference ability, and perfect protection functions. The whole machine is controlled by a high-speed single-chip microcomputer, with a high degree of automation, with automatic discharge and discharge alarm functions. The instrument has high test accuracy and easy operation, which can realize the rapid measurement of transformer direct resistance.Ⅱ: Technical Parameters of the transformer ratio tester:

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
