Option
Description
Right
Use this option if the station is at the right edge of water or an obstruction (i.e., sandbar, pylon
or large boulder).
Open water
Use this option to configure the edge as an open water environment (default).
9.
Select Distance to Vertical and enter the information.
10.
Select Set Depth and enter the information. If at an edge, the meter automatically sets this value
to 0.00.
a.
If Manual mode was selected in the Profiler setup, enter the total depth of water at this vertical
position.
b.
If Automatic mode was selected in the Profiler setup, put the probe at the bottom and push
OK
to set the maximum flow depth at the value shown.
Note: The maximum depth of a vertical probe is the measured inmersion plus the offset.
11.
If Left or Right was selected in Step
8
, enter an edge factor for the vertical. Select a factor from
the list or User-defined. For User-defined values, enter a roughness factor between 0.50 (very
rough) and 1.00 (smooth). The roughness factor is relevant only for right angled cross sections. It
is used as a factor in the calculation of the discharge proportion of edge areas. For example:
• Smooth edge with no vegetation (e.g., concrete, steel, cement)— 0.8 to 0.9
• Brick sides with vegetation— 0.7
• Rough walls with heavy vegetation—0.6 to 0.5
12.
Enter the stage reference. The stage reference is usually an elevation value from an object that
cannot be moved (e.g., a survey marker, staff gauge, bridge).
13.
Select Next to move to the next station.
14.
Select Distance to vertical.
15.
Enter the distance of the vertical to the reference point at the bank (e.g., tagline zero).
16.
Select Set Depth.
17.
Enter the maximum depth (manual mode) or measure the maximum depth (automatic mode).
18.
Enter the stage reference.
19.
Select Measure Velocity. Select an applicable velocity measurement method.
20.
Select a measurement point from the list. Obey the instrument prompts and adjust the sensor to
the correct depth. If the sensor has a depth option, adjust the sensor depth until the depth box is
green. This means the sensor is in at the correct position.
Note: Red indicates more adjustment is necessary. Yellow indicates the depth is close to the correct depth.
21.
Select Capture to start the measurement process.
22.
If necessary, the setup can be changed and the measurement can be repeated. When the
measurement is complete, push
OK
to store the data.
23.
Repeat steps

for the other measurement points on the vertical.
24.
When all measurements for the station are complete, select Main or Verify results. Push
OK
to
return to the list of measurement points.

Description
Main
Returns to the station menu.
Verify
Shows the average velocity reading for the station based on the measurement method.
25.
Select Next to go to the next station.
26.
Repeat steps
14
–
25
for all of the remaining stations selected for velocity measurements.
27.
If the stop bank shows, select Edge/Obstruction. Repeat steps

. To examine the
measurement before exit, select Channel Summary.
28.
Select Save data and Exit. Enter a name for the file and push
OK
.
Note: A warning flag will show if the discharge in one or more segments is more than 5% of the total discharge.
