2. Components and Scope of Supply
The standard package for the AI-DPI-2300 includes the following items:
- 1 unit of Hydraulic Hand Pump Calibrator (Model AI-DPI-2300)
- 1 unit of Master Gauge (Range: 0-700 bar)
- 3 Nos. Reducers (1/4", 1/2", 3/4")
- Instruction Manual (this document)
- Calibration Certificate Traceable to National Standards (NABL)

3. Setup and Connection
- Preparation: Ensure the calibrator is placed on a stable, level surface. Verify all connections are clean and free from debris.
- Connect Master Gauge: Attach the provided master gauge to the designated port on the calibrator. Use appropriate thread sealant if necessary to ensure a leak-free connection.
- Connect Unit Under Calibration (UUC): Connect the instrument to be calibrated (UUC) to the other port on the calibrator. Use one of the supplied reducers (1/4", 1/2", 3/4") if the UUC's port size differs from the calibrator's connection. Ensure a secure and leak-free connection.
- Fluid Filling (Hydraulic Mode): For hydraulic pressure generation, ensure the reservoir is filled with the appropriate calibration fluid. Refer to the fluid specifications for compatibility.

4. Operating Instructions
4.1. Pressure Generation
- Select Pressure Mode: Use the manual selector valve to switch the calibrator to pressure generation mode.
- Initial Pressure Build-up: Operate the hand pump handles to build up initial pressure. The adjustable stroke mechanism allows for efficient pressure generation with reduced effort.
- Fine Adjustment: Once near the desired pressure, use the fine vernier control for precise and stable pressure adjustments. The needle valve can be used for minor pressure release or stabilization.
- Reading: Compare the reading on the UUC with the master gauge.
- Pressure Release: To release pressure, slowly open the needle valve or the dedicated pressure release knob.

4.2. Vacuum Generation
- Select Vacuum Mode: Use the manual selector valve to switch the calibrator to vacuum generation mode.
- Generate Vacuum: Operate the hand pump handles to generate the desired vacuum level.
- Fine Adjustment: Use the fine vernier control for precise vacuum adjustments.
- Reading: Compare the reading on the UUC with the master gauge.
- Vacuum Release: To release vacuum, slowly open the dedicated vacuum release valve.

5. Maintenance
- Cleaning: Regularly clean the exterior of the calibrator with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Fluid Management: For hydraulic operation, periodically check the calibration fluid level and quality. Replace fluid as recommended by manufacturer guidelines or if contamination is suspected.
- Seal Inspection: Inspect all seals and O-rings for wear or damage. Replace any compromised seals to maintain pressure integrity.
- Storage: Store the calibrator in a clean, dry environment, away from extreme temperatures and direct sunlight. Ensure all valves are closed and pressure is released before storage.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Cannot build pressure/vacuum | Loose connections, worn seals, insufficient fluid (hydraulic mode), selector valve in wrong position. | Check all connections for tightness. Inspect and replace seals if necessary. Ensure fluid reservoir is adequately filled. Verify selector valve is set to the correct mode (pressure or vacuum). |
| Pressure/Vacuum drifts | Minor leaks, faulty needle valve, temperature fluctuations. | Check for small leaks at connections. Inspect needle valve for proper seating. Allow system to stabilize at ambient temperature. |
| Difficulty in fine adjustment | Vernier control mechanism obstruction or damage. | Clean the vernier mechanism. If damage is suspected, contact customer support. |
