It can be conveniently and accurately used to calibrate various models of single-phase or three-phase DC resistance testers currently produced in the market.
The three-phase DC analog resistance calibration device is designed specifically for the calibration of the above-mentioned instruments. It solves the problems of high current, high power, and adjustable resistance that are difficult to achieve with physical standards. It uses a color touch screen display to set calibration parameters and has a rare one key quick operation function. The Chinese menu operation prompts make the operation simple and intuitive. This calibration device has a calibration report that automatically inputs data through a laptop to complete the report.

1. Portable three channel verification three-phase DC resistance tester. At the same time, verify the three-phase resistance values and calculate the balance of the three-phase resistance.
2. Large screen touch display
3. The verification report is automatically generated and can be directly output through a computer connection
