Each functional module communicates with the control module 110 through a standard interface to ensure accurate data transmission. The diverse configuration of the functional modules meets different test requirements and enhances the flexibility and applicability of the device.

[0030] Among them, the control module 110 is used to call at least one matching functional module to perform pin function detection on the object module based on the type of the object module installed at the detection interface 120.

[0031] The control module 110 identifies the object module model through a preset program and automatically selects the corresponding functional module for detection to ensure the efficiency and accuracy of the detection process. Each functional module works independently without interference, and the detection results are real-time fed back to the control module 110 for easy and quick problem diagnosis.
