3. Velocity Measurement:

   • Position the probe in the airstream and take multiple readings to determine the average air velocity.
   • Adjust the probe’s position if needed to ensure accurate measurements.

4. Differential Pressure Measurement:

   • Connect the tubing to the appropriate ports on the Fluke 922 and to the measurement points (e.g., across a filter or coil).
   • Take readings to identify pressure drops and compare them to standard values or previous measurements.

5. Data Logging:

   • Use the logging function to record measurements over time for detailed analysis and reporting.
   • Review logged data to identify trends and make informed maintenance decisions.

6. Maintenance:

   • Keep the instrument and probes clean and free from debris.
   • Regularly check the condition of the probes and tubing for any signs of wear or damage.
   • Calibrate the instrument periodically to maintain measurement accuracy.
