9、 Functional Features

1. The operation and control are carried out by the touch screen and control panel of the device itself. If curve analysis is not required, a computer is not required.

2. If curve analysis is required, a computer can be equipped to only perform data and curve recording functions without equipment control, avoiding the need for testers to alternate between the computer and equipment, making it more user-friendly.

3. The equipment has a test parameter memory function, which does not require setting for each test under the same test conditions, and the last test setting parameters will still be remembered when the power is turned off.

4. The experimental interface is simple and clear, with explanatory curves. Different parameters result in different curve trends, making it easy to understand.

5. The control panel is simple, with clear functional labeling and easy operation.

6. Can record and display simultaneouslyshow10Record the second experiment to facilitate comparative analysis of experimental data. And any set of data that is not ideal can be discarded at any time.

7. increase了UDisk download function, which can directly download the test records in the devicetoUIn the plate.

8. If equipped with a computer, detailed test reports can be generated, including specific information for each group, comprehensive information for multiple groups, and curves.

9. The equipment testing interface adopts a dashboard and real-time display of numbers, which is more convenient for viewing the testing process.

10. The equipment has a safety warning prompt. The test cannot start without closing the test chamber door, and a warning will pop up. When it is at full capacity (i.e. no output from the high-voltage transformer), a warning will pop up. If the door is opened during the test, the test will automatically end.

11. Using Bluetooth data transmission to solve the trouble of wall blocking and long-distance operation safety and reliability;

12. The equipment is equipped with a three color alarm light. When the green light is on, it indicates that the box door is well closed and the test can begin. When the yellow light is on, it indicates that the test box door is open and the sample can be replaced. When the red light is on, it indicates high voltageYu0.5KVDo not open the door at this time. The warning light will flash and sound an alarm during the discharge process after the DC test is completed. (Summary: The green light box door is closed well, the yellow light is opened with caution, and the red light has high voltage)
