Follow these steps to set up your AI-DPI-2200 calibrator for operation:
- અનપેકીંગ: પેકેજિંગમાંથી બધા ઘટકો કાળજીપૂર્વક દૂર કરો. પરિવહન દરમિયાન નુકસાનના કોઈપણ ચિહ્નો માટે તપાસ કરો.
- 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. ઓપરેટિંગ સૂચનાઓ
The AI-DPI-2200 allows for precise generation of both pressure and vacuum. Familiarize yourself with the controls before operation.
4.1 Pressure Generation
- ખાતરી કરો કે બધા જોડાણો સુરક્ષિત છે.
- To generate pressure, repeatedly squeeze the hand pump handles. The master gauge will display the increasing દબાણ.
- 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. જાળવણી
Proper maintenance ensures the longevity and accuracy of your AI-DPI-2200 calibrator.
- સફાઈ: 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.
- સંગ્રહ: 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.
- ઓ-રિંગ રિપ્લેસમેન્ટ: 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.
- બેટરી રિપ્લેસમેન્ટ: 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.
- માપાંકન: 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. મુશ્કેલીનિવારણ
This section addresses common issues you might encounter with your calibrator.
| સમસ્યા | સંભવિત કારણ | ઉકેલ |
|---|---|---|
| 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 | Lack of lubrication; Internal debris. | Consult with INSTRUKART support for guidance on lubrication or internal cleaning. Do not attempt to disassemble without proper knowledge. |
