I. Performance Features:

1. Equipped with microcomputer control, the panel features at least 16 touch switches for easy execution of various testing functions. It includes self-check and error reporting capabilities for convenient inspection and maintenance.

2. Comprehensive self-inspection and self-protection features ensure that the circuit can quickly cut off the output and emit both audio and visual alerts during overload or excessive range, reducing unnecessary losses caused by improper operation.

3. Intelligent operation: With just one button, the universal relay's full parameters can be measured, and all data is automatically printed.

4. The display features functional display units, allowing for a clear reflection of the working status from the screen.

5. All printed data is in Chinese characters, such as "Closing Voltage," "Opening Voltage," and "Normal Open Closing Time," etc. (Note: Digital tube display is used without printing functionality).
