Product Feature And Application

1. Use a high-speed, high-integration microprocessor to sample and control.

2. Use USB to connect the notebook PC and device.

3. Communication wireless Bluetooth interface between the laptop and instruments.

4. The hardware cassette mechanism adopts DDS (from America), and can correctly detect the breakdown distortion, swell, shift, tilt, inter-turn short circuit deformation, and contacting short circuit inter-phase.

5. High-speed, dual channel, 16-bit A/D sampling (the wave from the curve will change obviously if the tapping switch during the field tests.).

6. The software can adjust the output signal range, the maximum amplitude peak±10V.

7. The computer automatically generates the test results to be Word document.

8. Use precision, high stability components, the same phase repeat test, and measurement repetition rate >99.5%.

9. Finished circuit boards, surface specially treated with anti-water pollution and harmful gases.

10. The device has two measurement systems: linear scan and sectional scan.

11. Amplitude-frequency characteristics comply with the national technical specifications.

12. Test data automatic analysis system, horizontal compare the similarity of A,B ,C, the results as below:
