## Calibration Logs Module User Guide
### 1. Purpose
The **Calibration Logs** module is used to track the calibration status of all site instruments and welding / test equipment.
It provides:
- Central register of instruments (name, model, serial, quantity)
- Calibration certificate and user guide PDFs
- Due date monitoring with color indications
- Notifications when calibration is due within 20 days
- Automatic sync from **NAKS Welding Equipments** for welding machines
---
### 2. How to Access
1. Login to the application.
2. From the left menu, navigate to **QA → Calibration Logs**.
3. The page will open with a DevExtreme DataGrid listing all calibration records.
---
### 3. Column Overview
Key columns (left to right):
- **Certification Document** (`certification_document`):
- PDF icon link to the calibration certificate.
- Filled automatically by the PDF upload sync script.
- **User Guide** (`user_guide`):
- Optional PDF link for instrument user/operation manual.
- **Instrument** (`instrument`):
- Category selection:
- `Civil Works Test Equipment`
- `Piping/Mechanical Test Equipment`
- `Instrument Test Equipment`
- `Painting and Coating Test Equipment`
- `Electrical Test Equipment`
- `Welding Equipment`
- **Item No** (`item_no`): Line/item number from the register.
- **Name** (`equipment_name`): Instrument or equipment name.
- **Manufacturer** (`manufacturer`), **Model No** (`model_no`), **Serial No** (`serial_no`), **Quantity** (`quantity`)
- **Passport / Certificate No** (`passport_certificate_no`)
- **Place of Calibration / Verification** (`place_of_calibration_verification`):
- `Laboratory`, `In house verification`, or `In house calibration`.
- **Calibrated By** (`calibrated_by`)
- **Calibration Frequency (months)** (`calibration_frequency`):
- Integer value in months.
- **Calibration Certificate No** (`calibration_certificate_no`)
- **Calibration Date** (`calibration_date`)
- **Calibration Due Date** (`calibration_due_date`)
- **Deviation Ratio** (`deviation_ratio`)
- **Status** (`status`):
- `In use`, `Out Of service`, `Repair`, `Calibration-Verification`
- **Remarks** (`remarks`) and **Comments** (`comments`)
System fields:
- **source_module**, **source_id**: Link to source modules (e.g. `welding_equipment`).

### 4. Row Colors & Due-Date Logic
Rows are color-coded based on `calibration_due_date`:
- **Expired (red row)**: `calibration_due_date` \< today.
- **Due Soon (yellow row)**: `calibration_due_date` is between today and today + 20 days.
- **Normal (white row)**: More than 20 days until due date.
The same due date is used by the notification command:
- Artisan command: `php artisan notifications:check-calibration-due`
- Notification code: `notification_calibration_due_soon`
---
### 5. PDF Upload and Sync
Calibration certificates are stored under:
- Storage path: `storage/documents/004_QA/0020_Calibration`
Usage:
1. Open **QA → Calibration Logs**.
2. Click the **Upload** button (top of the grid).
3. Select table **`calibration_logs`** and drop one or more PDF files.
4. The sync script `cron/pdf-db-calibration-logs-sync.blade.php` tries to match files to rows:
- First by `calibration_certificate_no`
- Then by `passport_certificate_no`
- Finally by `equipment_name`
5. When a match is found, the `certification_document` field is updated with the PDF path and the PDF icon becomes visible in the grid.
> Recommendation: Name files starting with the **Calibration Certificate No** (e.g. `C-12345 ... .pdf`) to ensure reliable matching.

### 6. Notifications Configuration
The 20-day notification uses:
- Command: `notifications:check-calibration-due`
- Notification code: `notification_calibration_due_soon`
To configure which user levels receive this notification:
1. Go to **Settings → Specific Permissions → Notification Settings**.
2. Find **“Calibration Due Soon”** (`notification_calibration_due_soon`).
3. Select the user levels (e.g. `Admin`, `Quality Staff`, `QC Manager`).
4. Click **Update**.
When the command runs (via scheduler or manually), users in these levels will see **“Calibration Due Soon”** items in the notification bell.
---
### 7. NAKS Welding Equipments Sync
When a record is created or updated in **NAKS Welding Equipments** (`welding_equipment` table):
- The helper `syncCalibrationFromWeldingEquipment()` is called from `AdminController`.
- It creates or updates a corresponding `calibration_logs` record with:
- `instrument = "Welding Equipment"`
- Basic identity fields (name, manufacturer, model, serial)
- `passport_certificate_no` from `attestation`
- `calibration_date` from `date_of_issue`
- `calibration_due_date` from `valid_until`
- `status` calculated from due date (`Valid`, `Due Soon`, `Expired`)
This ensures welding machines are automatically visible in the Calibration Logs register without manual re-entry.
