Step 1
Station parameters defined for Velocity
Measurement, e.g., parameters of station defined for
velocity measurement are the following,
a) Location X: 1.534m,
b) Location Y: 2.978m,
c) Water Depth: 1,125m,
d) Measurement Depth: 0.6m,
e) Velocity Method: Two Point,
f) Comment.
g) To add station and continue velocity measurement,
i). Press the Right Soft Key.
h) To CANCEL a new station,
i). Press the Left Soft Key.
The water depth at each station can either be based on pressure sensor measurements
or manually entered by the user. To perform pressure sensor measurement the Enter
Key is pressed on the Water Depth and Measurement Depth parameter.
Step 2
Pressure Sensor (PS) Calibration allows the user to
perform pressure sensor calibration. The screen is
displayed before the first pressure sensor
measurement is performed or when the Air Pressure
Cal. Period expired.
a) To perform PS Calibration,
i). Press the Right Soft Key.
b) To CANCEL PS Calibration,
i). Press the Left Soft Key.
Step 3
Pressure Sensor (PS) Total Depth screen allows
the user to perform depth measurement. The tilt
sensor or bubble should be used to keep the
instrument vertical.
a) To perform Depth Measurement,
i). Press the Right Soft Key.
b) To CANCEL PS Calibration,
i). Press the Left Soft Key.
The FlowTracker2 ADV Probe should be kept vertical during the pressure sensor
measurements. Any angle on the probe will impact the pressure sensor measurements
because the probe is off center of the wading rod.
