Features
3. During the test, the test result is available and the graphic distribution of abnormal points in each profile is shown at any time. Meanwhile, wave train figure, curve graph and data list of each profile may be shown;
4. During the test, sampling delay and amplification factor may be adjusted at any time;
5. With high definition LCD screen, waveform, wave speed and amplitude of multiple tested profiles may be clearly observed, and the quality of whole pile in the test is very clear.
6. It adopts touch screen and user-friendly interface, which is simply, easy to learn and convenient to operate;
7. With high-capacity SD card, there is no need to worry about the storage space of test data;
8. Built-in high-performance and capacity lithium battery may satisfy fieldwork for long time.
9. Various USB ports may be used for data transmission or software update within the instrument.
10. Test data of the same project is saved under the folder created with the title of the project for easy and reliable management.
