2. Setup
Proper setup is crucial for accurate calibration. Follow these steps to prepare your AI-2200 calibrator:
- Connect the Master Gauge: Attach your high-precision master gauge to the designated port on the calibrator. Ensure a secure, leak-free connection.
- Connect the Unit Under Calibration (UUC): Connect the instrument you wish to calibrate (UUC) to the other port using the appropriate hose and reducers. The calibrator includes various reducers (1/8" BSP(F), 1/2" BSP(F), 3/8" BSP(F)) to accommodate different connection types.
- Select Medium (for Hydraulic models): If using a hydraulic model, ensure the reservoir is filled with the appropriate fluid (water or oil) as required for the pressure range. The AI-2200 is primarily pneumatic, but some variants may support hydraulic operation.
- Verify Connections: Double-check all connections to prevent pressure leaks during operation.

3. Operating Instructions
The AI-2200 calibrator is designed for both pressure and vacuum generation. Follow these steps for operation:
- Generating Pressure:
- Ensure all connections are tight.
- Close the release valve (if open).
- Operate the hand pump handles to generate the desired pressure. Observe both the master gauge and the UUC.
- Adjust pressure finely using the fine adjustment knob, if available.
- Generating Vacuum:
- Ensure all connections are tight.
- Switch the calibrator to vacuum mode (if applicable, typically by a selector switch or piston pin adjustment).
- Operate the hand pump handles to generate the desired vacuum. Observe both the master gauge and the UUC.
- Releasing Pressure/Vacuum: Slowly open the release valve to gradually decrease pressure or return to ambient conditions.

4. Maintenance
Regular maintenance ensures the longevity and accuracy of your calibrator:
- Cleaning: Keep the calibrator clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Storage: Store the calibrator in a dry, cool place, away from direct sunlight and extreme temperatures.
- Seal Inspection: Periodically inspect O-rings and seals for wear and tear. Replace them if any damage is observed to maintain pressure integrity.
- Calibration: For continued accuracy, it is recommended to have the calibrator itself recalibrated by an authorized service center at regular intervals.
5. Troubleshooting
If you encounter issues with your AI-2200 calibrator, consider the following:
- Pressure/Vacuum Loss: Check all connections for tightness. Inspect hoses and seals for any visible damage or leaks.
- Inaccurate Readings: Ensure both the master gauge and the UUC are properly connected and functioning. Verify that the calibrator is set to the correct mode (pressure or vacuum).
- Difficulty Generating Pressure/Vacuum: Check for blockages in the system. Ensure the release valve is fully closed when generating pressure/vacuum.
For persistent issues, contact customer support.
