- Operated and controlled by the touch screen and control panel of the device itself.If curve analysis is not required, it can not be equipped with a computer.
- If curve analysis is required, a computer can be equipped to only perform data and curve recording functions, without controlling the equipment, avoid the need for testers to alternate between the computer and equipment, make it more user-friendly.
- The equipment has the function of test parameter memory.The same test conditions do not need to be set for each test, and even if the power is cut off, the last test setting parameters will still be remembered.
- The test interface is simple and clear, and is equipped with schematic curve description, different parameters, different curve trends, easy to understand.
- The control panel is simple,with clear functional labeling and easy operation.
- It can record and display 10 test records simultaneously, facilitating comparative analysis of test data, and any set of data that isn't ideal can be discarded at any time.
- Added USB download function,which can download the test records in the device directly to the USB.
- If equipped with a computer, a detailed test report can be generated, including each group of specific information,multiple groups of comprehensive information and curves.
- The equipment testing interface adopts a dashboard and digital display mode that is both simultaneously and real-time, making it more convenient to observe the testing process.
- The equipment has safety warning prompt, the test cannot start without closing the test chamber door, and a warning will pop up and the warning will pop up when the full degree (i.e. no output from the high-voltage transformer), and the test will automatically end if the door is opened during the test.
- Using Bluetooth data transmission to solve the problem of being blocked by isolation walls, remote operation is safe and reliable.
- The equipment is equipped with three color alarm light. When the green light is on, it indicates that the chamber door is closed well and the test can start; when the yellow light is on, it indicates that the chamber door is open and the sample can be replaced; when the red light is on, it indicates that the high voltage is higher than 0.5kV and the chamber door shouldn't be opened at this time. The warning light will flash and sound an alarm during the discharge process after the DC test is completed.(Green light:The chamber door is closed properly; Yellow light: Be careful when opening the door; Red light: There's high voltage)
