3. Configuración
Follow these steps to set up your AI-DPI-2200 calibrator for operation:
- Desembalaje: Retire con cuidado todos los componentes del embalaje. Inspeccione si presentan daños durante el transporte.
- 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. Instrucciones de funcionamiento
The AI-DPI-2200 allows for precise generation of both pressure and vacuum. Familiarize yourself with the controls before operation.
4.1 Pressure Generation
- Asegúrese de que todas las conexiones sean seguras.
- To generate pressure, repeatedly squeeze the hand pump handles. The master gauge will display the increasing de presión.
- 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.

5. Mantenimiento
Proper maintenance ensures the longevity and accuracy of your AI-DPI-2200 calibrator.
- Limpieza: 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.
- Almacenamiento: 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.
- Reemplazo de junta tórica: 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.
- Reemplazo de batería: 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.
- Calibración: 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. Solución de problemas
This section addresses common issues you might encounter with your calibrator.
| Problema | Posible causa | Solución |
|---|---|---|
| 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 | Falta de lubricación; Residuos internos. | Consult with INSTRUKART support for guidance on lubrication or internal cleaning. Do not attempt to disassemble without proper knowledge. |
