Automated Beam Check
Automated Beam Check function in the data collection menu allows the user to perform
beam check during any stage of the velocity measurement. The Automated Beam
Check function operations, conventions and graphic display features are defined under
Automated Beam
Check.
Automated Beam Checks performed during the discharge measurement are stored in
FlowTracker2 file (.ft) that was created for the measurement site.

PS Calibration
The PS Calibration function in the data collection menu allows the user to perform
Pressure Sensor Calibration during any stage between point velocity measurements.
Frequent calibration of pressure sensor for atmospheric or air pressure changes during
the measurement will improve the accuracy of pressure measurements. The variation
in atmospheric or air pressure will impact the accuracy of pressure measurements.
