The KDZR-XY single-phase circuit direct resistance standard device adopts precision electronic circuits, potential difference meter circuits, and current comparator technology. Using Ohm's law relationship, it simulates a series of high-precision DC standard voltages under high currents. It is a standard equipment for verifying DC circuit resistance testers and has the characteristics of high accuracy, small size, and easy use. It can be conveniently and accurately used to calibrate various models of single-phase or three-phase DC resistance testers currently produced on the market.

1. Portable verification DC resistance tester. At the same time, verify the three-phase resistance values and calculate the balance of the three-phase resistance.
2. Portable verification circuit resistance tester. At the same time, verify the three-phase resistance values and calculate the balance of the three-phase resistance.
3. Single channel input current range 0.1A-300A
4. A single-phase DC analog resistance calibration device, with adjustable high current, high power, and resistance values for the standard.
5. The standard equipment has a single key quick operation function and Chinese menu operation prompts.
6. The operation is simple and intuitive. After upgrading, this calibration device has a calibration report that can be automatically completed by inputting data through a laptop.
7. This device meets the latest standards: JJG 1052-2009 Loop Resistance Tester, Direct Resistance Tester Verification Regulations.
