I. Performance Features:

The machine is controlled by a microcomputer, featuring at least 16 touch switches on the panel for easy completion of various test functions. It is equipped with self-check and error reporting features 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: simply press a button to measure all parameters of a general relay and automatically print all data.

4. The display features a functional display unit, 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," "Normal Closing Time," etc. (Note: Digital tube display is used, without printing function.)

II. Technical Specifications:

1. Output Voltage Range: Continuously adjustable from 0 to 500V, with a high output capacity of 6000VA, over-range protection at 500V, and an accuracy of ±0.25%.
