ADS Environmental Services Portable FlowShark Pulse QR 775006 A2 - Manual (Page 156)

Parameter Settings 6-57
Calibration and Calculation Menu (CAL)
This menu enables you to adjust the depth sensors and the settings for flow velocity
measurement. It also allows you to generate simulations involving relay switching
events, analog outputs, and flow.
Menu selection
CAL: Level
This submenu enables you to calibrate the depth sensors for various purposes, such as
adjusting the depth offset to compensate for structural conditions. Calibration
involves entering a reference value obtained by performing an independent
measurement, such as using a precision ruler to conduct a manual measurement.
Adjust all active depth sensors according to this reference value.
The follow screen displays after confirming a calibration:
Calibrating depth
This screen displays the current depth level and range of fluctuation, including
minimum and maximum values, measured by the sensor. This data allows you to
access the current flow depth conditions (e.g., surface roughness). The best results
are obtained under conditions where little variation exists between the minimum and
maximum values. Accept the current depth reading after reviewing it against a
corresponding reference value by pressing the Enter ( ) key.
Enter the manual (i.e., field-confirmed) value in the reference field on the next menu.
