2, A variety of technical indicators fully meet the Ministry issued by the Ministry of power DL/T624-1997 "relay protection microcomputer test device technical conditions" standard.

3, Stand-alone operation, built-in high-performance industrial computer, clocked at 1.7GHz, memory 2G, hard disk 16G, running Windows XP operating system.

4, the domestic industry first imported stainless steel wire drawing panel, acrylic digital keyboard, and a touch mouse, overcome the trackball mouse operation is not flexible and easily damaged weaknesses, and use 8.4 inch TFT LCD, resolution 800 * 600, the single overall operation is convenient, durable.

5, The main control board uses DSP+FPGA structure, 16 DAC output, a high density of Jiboke sine wave 2000 points per cycle, greatly improved the quality of waveform improves the test accuracy.

6, The use of high fidelity linear amplifier amplifier, both to ensure the accuracy of small current, but also to ensure the stability of large current.

7, The use of USB interface and PC communication directly, without any transfer line, easy to use.

8, Can be connected to the notebook computer. Notebook computer and industrial computer use the same set of software, no need to re learn the operation method.

9, With an independent dedicated DC auxiliary voltage source output, the output voltage of 110V (1A), 220V (0.6A). To provide for the use of DC power supply of the relay or protective device.

10, With the software self calibration function, to avoid the need to open the chassis by adjusting the potentiometer to calibrate the accuracy, thereby greatly improving the accuracy of the stability.
