3.2 Сample Preparation and Loading

1. Prepare your fluid sample according to your testing protocol.
2. Кылдаттык менен төкample into the rotor cup, ensuring the bob is fully immersed and the fluid level is appropriate for measurement. Avoid air bubbles.

3.3 Өлчөө жүргүзүү

1. Using the control panel or the ORCADA software, select the desired test parameters (e.g., shear rate, temperature).
2. Initiate the measurement cycle. The viscometer will begin rotating the rotor cup, and the transducer will measure the induced angle of rotation of the bob.
3. Monitor the display for real-time readings or observe the data acquisition through the ORCADA software.
4. Once the measurement is complete, record the data.

3.4 Data Acquisition and Analysis (with ORCADA Software)

For automated control and comprehensive data analysis, connect the viscometer to a computer running OFITE's ORCADA software. The software allows for:

• Real-time data plotting.
• Customizable test profiles.
• Маалыматтарды сактоо жана экспорттоо.
• Advanced rheological calculations.

4. Техникалык тейлөө

Proper maintenance ensures the longevity and accuracy of your Model 900 Viscometer.

4.1 Тазалоо

• After each use, thoroughly clean the rotor cup and bob with an appropriate solvent for the tested fluid.
• Wipe down the exterior of the viscometer with a soft, damp кездеме. Финишке зыян келтирүүчү абразивдүү тазалагычтарды же эриткичтерди колдонуудан алыс болуңуз.
• Ensure no fluid enters the internal components of the viscometer.

4.2 Калибрлөө

Regular calibration is crucial for maintaining measurement accuracy. Use the provided calibration accessories and follow the calibration procedure outlined in the ORCADA software or a separate calibration guide (if provided by OFITE). It is recommended to calibrate the instrument at regular intervals or if you suspect measurement inaccuracies.

4.3 Сактоо

When not in use, store the viscometer in its carrying case in a clean, dry environment, away from extreme temperatures and direct sunlight.
