Measurement Wizard
The Hydrologist selects to start a new measurement within the
WinRiver II
application. Once the Hydrol-
ogist enters all of the background information on the site where the measurement will be performed, the
software
will then automatically detect whether an ADCP is connected and which ADCP product it is.
Use the
Transducer Depth
field to set the depth from the water level to the
center of the slant beam transducer faces.
Enter the
Magnetic Variation
for the site.
See Chapter 3 Tutorials and Chapter 7 Using the Measurement Wizard in the WinRiver II
User’s Guide.
Run Built-In Tests
The StreamPro is commanded to perform a BIT test on power up. On the
Acquire
menu, click
Execute
ADCP Test
to verify the ADCP is functioning properly.
See Chapter 3 Tutorials and Chapter 9 QA/QC in the WinRiver II User’s Guide.
Compass Calibration
Next, the Hydrologist performs a compass calibration. After ensuring that the system is well away from
sources of magnetic interference, the Hydrologist starts the compass calibration within the application
and then either: slowly rotates the StreamPro as suggested by the application (tethered boat/SxS) or
slowly drives the RC boat in a circle. During the calibration process, feedback is provided to the user as to
the quality of the collected magnetic field data at each partition of the 360
°
of rotation.
On the
Acquire
menu, click
Execute Compass Calibration
. When the calibration starts, select
No
for
the
Use Pitch/Roll
selection. In normal river discharge circumstances, using the “No” Pitch and Roll se-
lection is sufficient.
The no Pitch/Roll calibration (also called a single-tilt
calibration) requires two rotations while the ADCP is
on a flat, level surface.
