Product Description

GDZRC-40U DC Winding Resistance Tester 


I. General Information
GDZRC-40U DC Winding Resistance Measuring Device is designed to measure DC resistance of inductive devices, such as transformers and power inductors. Adopts new power supply technology, it has the characteristics of small size, light weight, large output current, good repeatability, strong anti-interference ability and perfect protection function. The whole machine is controlled by high-speed single-chip microcomputer, with high degree of automation and automatic discharge and discharge alarm function. The instrument has high precision and easy operation, and it can realize rapid measurement of transformer DC resistance.


II. Features

1. The whole machine is controlled by high-speed single-chip microcomputer, with high automation and easy operation.
2. Using new power supply technology, with multiple current gears and wide measuring range, it is suitable for DC resistance measurement of large and medium-sized transformers.
3. Perfect protection function, which can reliably protect the impact of back EMF on the instrument, and the performance is more reliable.
4. Audible discharge alarm and clear discharge indication, to avoid error and ensure safety.
5. Fast response speed, the on-load tap changer can be directly converted in the measurement state, and the instrument automatically refreshes the data.
6. Intelligent power management technology, the instrument works in the minimum power state, effectively saving energy and reducing heat.
7. 320*240 dot matrix ultra-small pixel 65K true color LCD.
8. With calendar clock and power-down storage, 1000 sets of test data can be stored and accessed at any time.
9. It is equipped with RS232 (reserved interface) and USB interface (U disk storage).
