20A Portable transformer DC resistance tester
Product overview
Transformer DC resistance measurement is a common test item of semi-finished product, finished product factory test, installation, handover test and preventive test of power department in transformer manufacturing, which can effectively find the manufacturing defects of transformer coil material selection, welding, loose connection parts, missing strands, broken wires and other hidden dangers after operation. Dc resistance tester is a fast test equipment for measuring DC resistance of large transformers, transformers, generators and motors.
Functional characteristics
1. The instrument has wide resistance measurement range, high resolution and multi-current gear selection.
2. The instrument has automatic test (blind test) function.
3. The instrument has perfect anti-potential protection function.
4. The instrument has a temperature conversion function, which automatically converts the resistance value to the standard temperature.
5. Longitudinal testing of the DC resistance of the on-load regulator transformer can be done in one go.
6. The instrument has the characteristics of high measuring precision, anti-interference, shock-proof and easy to carry.
7. 5.0-inch 65K color touch screen for easy operation.
8. Built-in large non-volatile memory, can store 500 sets of data.
9. Built-in high-speed micro thermal printer, can print measurement data.
10. Built-in high precision clock, real-time display time.
11. With U disk storage function.
