## 5. Common Issues and Handling

### 5.1 Inspection Anomaly Handling

| Issue Phenomenon | Possible Cause | Handling Method |
|-----------------|----------------|----------------|
| Cannot submit inspection | Required fields not filled | Check if inspection result has been selected |
| Abnormal inspection result (NG) | Detected data does not meet standards | Handle equipment issue according to exception process |
| Cannot load inspection items | Inspection items not configured | Contact administrator to configure inspection items |
| PDA cannot submit data | Network exception or incomplete data | Check network or supplement data and resubmit |

**[Important]** When inspection result is NG, equipment must stop using and be re-inspected after the issue is resolved.

---

### 5.2 Inspection Process Anomaly

| Issue Phenomenon | Possible Cause | Handling Method |
|-----------------|----------------|----------------|
| Equipment cannot start | Inspection not completed or failed | Complete inspection and ensure result is OK |
| Can produce without inspection | System control not enabled | Check inspection and equipment control binding configuration |

**[Note]** It is recommended to enable the "Mandatory Inspection Before Startup" mechanism to avoid missed inspection risks.

---

## 6. Inspection Data Management Standards

### 6.1 Data Integrity Requirements

**[Important]**  
To ensure the authenticity and effectiveness of inspection data, the following requirements must be met:

- All equipment must have inspection items configured
- Inspection must be completed before each production
- Inspection results must be filled in truthfully without falsification
- Inspection anomalies must be recorded and handled
- Inspection records must be associated with equipment and personnel

---

### 6.2 Data Management Rules

| Rule | Description |
|------|-------------|
| Data Authenticity | Inspection data must truly reflect equipment status |
| Data Completeness | Inspection records must be complete without missing entries |
| Data Timeliness | Inspection data must be entered in real-time or during the shift |
| Data Relevance | Inspection records must be associated with equipment, personnel, and time |

---

### 6.3 Inspection Frequency Recommendations

| Inspection Type | Recommended Frequency | Description |
|----------------|---------------------|-------------|
| Startup Inspection | Once per shift/day | Must be performed before startup |
| Process Inspection | According to process requirements | Critical process equipment |
| Routine Inspection | Daily/Weekly | Equipment operation status check |
| Special Inspection | As needed | After anomaly or maintenance |

**[Tip]**  
Different inspection frequencies can be set according to equipment importance to achieve refined management.
