Step 4
Measurement screen display the point velocity
measurements required at each fractional depth, e.g.,
the fractional depths for the two point method at
station 2m with a water depth of 1m are the following,
• 0.2 x water depth, 0.2m
• 0.8 x water depth, 0.8m
a) To select a fractional measurement depth,
i). Use the up or down arrow key to scroll through
the measurement options,
b) To continue to velocity measurement,
i). Press the enter key.
c) To open data collection menu,
i). Press the Right Soft Key.
d) To REVERT to add station screen,
i). Press the Left Soft Key.
The order in how the point velocity measurements are performed at each fractional
depth is not set and the user can perform the measurements in any order. The
software will start at the bottom of each station for pressure sensor measurements.
