Prepare the probe by removing debris, ensuring free propeller spin, and cleaning as needed.
Orient the probe into flow, adjust handle, press RESET to start measurements, and ensure computer is active.
Determine flow by calculating cross-sectional area and using the formula Q = V x A.
Understand low power mode activation and battery life considerations for extended operation.
Channel friction, water surges, turbulence, and obstructions affect flow velocity and require averaging.
Learn methods for measuring velocity in small streams, large streams, and using the USGS 6 tens method.
Understand the main display and functions of MODE, MENU, SAVE, and RESET buttons for operation.
Learn to save data to memory, navigate locations, and overwrite or preserve existing data.
Access the setup menu by holding MENU; explore options like View, Delete, Units, and Calibration.
Select desired flow units (FT/S or M/S) from the setup menu and save the selection.
The calibration factor is factory set but can be adjusted within the setup menu if needed.
Separate and dry the probe handle; avoid submerging the computer unit.
The battery is non-replaceable; follow recycling procedures and ensure propeller spins freely.
Address propeller spin issues, magnet placement, computer connection, and blank displays.
