+# BLDI Pressure Gauge Model Classification Tool
+
+A VBA-based Excel tool for classifying pressure gauge model codes into product categories.
+
+## Features
+
+- **Automatic Classification**: Classifies model codes into 9 product categories
+- **High Performance**: Uses bulk array operations for fast processing (1000+ records in seconds)
+- **Priority-Based Logic**: Implements a decision funnel classification system
+- **Comprehensive Testing**: Includes full test suite with PRD validation
+
+## Categories (Priority Order)
+
+1. **喷涂产品** (Spray-coated) - Highest priority
+2. **卫生型隔膜表** (Sanitary diaphragm)
+3. **隔膜表** (Diaphragm)
+4. **差压表** (Differential pressure)
+5. **膜盒压力表** (Capsule)
+6. **精密压力表** (Precision)
+7. **电接点压力表** (Electric contact)
+8. **常规表** (Regular)
+9. **其他** (Other) - Default
+
+## File Structure
+
+```
+VBA/
+├── ClassModules/
+│   └── GaugeClassifier.cls     # Core classification logic
+└── Modules/
+    ├── MainModule.bas           # Excel I/O interface

+   ┌────────────────────────────────────┐
+   1 │ 型号代码       │ 产品分类    │
+   ├────────────────────────────────────┤
+   2 │ PYTH-100.A0...│              │
+   3 │ Y-040.Z0.200..│              │
+   └────────────────────────────────────┘
+   ```
+
+2. **Run classification**:
+   - Press `Alt + F8`
+   - Select `RunClassification`
+   - Click **Run**
+
+3. **View results** in column B
+
+### Alternative Methods
+
+#### Selection-based Classification

+3. Results appear in adjacent column
+
+#### Clear Results
+- Run `ClearClassifications` to remove classifications
+
+## Testing
+
+### Run All Tests
+1. Press `Alt + F11` to open VBA Editor
+2. Press `Ctrl + G` to open Immediate Window
+3. Run `TestClassifierLogic`
+4. View results in Immediate Window
+

+
+## Classification Logic
+
+### String Structure
+Model code format: `[表头]|[表盘]|[附件]|[法兰隔膜]`
+
+### Parsing Rules
+
+| Component | Description | Example |
+|-----------|-------------|---------|
+| **Head** | Everything before first `\|` | `PYTH-100.A0.531.M201.M06` |
+| **Main Model** | First word before `-` in head | `PYTH` |
+| **Flange** | Last section if starts with `F` | `FBP-251040.RF1.049.13...` |
+
+### Classification Rules
+
+1. **Spray-coated (喷涂产品)**
+   - Flange ends with `P` OR head contains `F6AP`/`F6BP`
+
+2. **Sanitary Diaphragm (卫生型隔膜表)**
+   - Head contains `F6A` or `F6B` (excluding spray variants)
+
+3. **Diaphragm (隔膜表)**
+   - Main model starts with `P`
+
+4. **Differential Pressure (差压表)**
+   - Main model starts with `YC`
+
+5. **Capsule (膜盒压力表)**
+   - Main model starts with `YE`
+
+6. **Precision (精密压力表)**
+   - Main model starts with `YB`
+
+7. **Electric Contact (电接点压力表)**
+   - Main model starts with `YX`
+
+8. **Regular (常规表)**
+   - Main model starts with `Y`
+
+9. **Other (其他)**
+   - Everything else (including empty strings)
+
+## Performance
+
+Typical performance on standard hardware:
+- **100 records**: ~0.01 seconds
+- **1,000 records**: ~0.05 seconds
+- **10,000 records**: ~0.5 seconds
+
+Uses bulk array operations (`Value2`) for optimal performance.
+
+## Troubleshooting
+
+### "No data found" error
+- Ensure data starts from cell A2
+- Check that column A contains model codes
+
+### Runtime error 1004
+- Make sure workbook is saved as `.xlsm` (macro-enabled)
+- Check macro security settings: **File → Options → Trust Center → Trust Center Settings → Macro Settings**
+
+### Incorrect classifications
+- Verify model code format matches expected structure
+- Check for extra spaces or special characters
+- Run `TestClassifierLogic()` to validate classifier logic
