3. Настройка
Follow these steps to set up your AI-DPI-2200 calibrator for operation:
- Распаковка: Аккуратно извлеките все компоненты из упаковки. Проверьте наличие повреждений, полученных во время транспортировки.
- Attach Master Gauge: Screw the provided master gauge onto the designated port at the top of the calibrator. Ensure it is hand-tightened securely to prevent leaks.
- Connect Unit Under Calibration (UUC): Connect the device to be calibrated (UUC) to the appropriate port using the supplied hose and reducers if necessary. Select the reducer that matches the UUC's connection size (1/4", 1/2", or 3/4").
- Battery Installation (for digital master gauge): If your master gauge is digital, ensure 2 x AAA batteries are correctly installed. Refer to the gauge's specific manual for battery compartment location and polarity.

4. Инструкция по эксплуатации
The AI-DPI-2200 allows for precise generation of both pressure and vacuum. Familiarize yourself with the controls before operation.
4.1 Pressure Generation
- Убедитесь, что все соединения надежны.
- To generate pressure, repeatedly squeeze the hand pump handles. The master gauge will display the increasinг давление.
- Use the fine adjustment knob (if present) to precisely set the desired pressure.
- To release pressure, slowly open the release valve.
Figure 5: Generating pressure by squeezing the handles.
4.2 Vacuum Generation
- To switch from pressure to vacuum mode, use the piston pin. This typically involves pulling out or rotating a pin located near the pump mechanism.
- Once in vacuum mode, repeatedly squeeze the hand pump handles to generate vacuum. The master gauge will display the decreasing pressure (negative values).
- To release vacuum, slowly open the release valve.

4.3 Master Gauge Usage
The calibrator is compatible with various master gauges, allowing for flexibility in calibration tasks.

5. Техническое обслуживание
Proper maintenance ensures the longevity and accuracy of your AI-DPI-2200 calibrator.
- Уборка: Wipe the calibrator with a soft, dry cloth after each use. Avoid using abrasive cleaners or solvents that could damage the finish or internal components.
- Хранилище: Store the calibrator in a clean, dry environment, away from extreme temperatures and direct sunlight. Use the original packaging or a protective case for storage.
- Замена уплотнительного кольца: Periodically inspect the O-rings for wear and tear. Replace them if they appear cracked, flattened, or damaged to maintain a proper seal. Spare O-rings are provided.
- Замена батареи: For digital master gauges, replace the 2 x AAA batteries when the low battery indicator appears or the display becomes dim. Ensure correct polarity during installation.
- Калибровка: For optimal accuracy, it is recommended to have the calibrator and master gauge professionally calibrated at regular intervals, typically annually, or as required by your quality system.
6. Поиск Неисправностей
This section addresses common issues you might encounter with your calibrator.
| Проблема | Возможная причина | Решение |
|---|---|---|
| Cannot generate pressure/vacuum | Loose connections; Damaged O-rings; Piston pin not correctly set for mode. | Check all connections for tightness. Inspect and replace O-rings if necessary. Ensure piston pin is fully engaged for the desired mode (pressure or vacuum). |
| Pressure/Vacuum leaks | Loose connections; Worn or damaged O-rings; Damaged hose. | Tighten all connections. Replace O-rings. Inspect hose for cracks or damage and replace if found. |
| Inaccurate readings on digital gauge | Low battery; Gauge needs calibration. | Replace batteries. Consider professional calibration of the master gauge. |
| Handles are stiff or difficult to pump | Недостаток смазки; внутренние обломки. | Consult with INSTRUKART support for guidance on lubrication or internal cleaning. Do not attempt to disassemble without proper knowledge. |
