CW Velocity Settings:
Zero Result on RSSI Fail –
If the Signal strength is poor in the water and if this setting
is enabled, instrument will return a result of zero for velocity. Otherwise, it will return the
last known velocity when the signal was above the minimum RSSI setting.
Zero Result on Spread Fail -
If the Signal quality is poor, i.e., turbulent in the water,
then if this setting is enabled will return a result of zero for velocity otherwise will return
the last known velocity when the signal was above the minimum signal spread setting.
Enable -ve (reverse) velocity –
This will enable velocity in both directions. Usually used
in tidal flows.
Enable over range limit –
The velocity can be configured for multiple ranges; if the
velocity exceeds the range, then when enabling this option, the velocity value provided is
the maximum range value (i.e., 1673 mm/s). If not enabled, the value will wrap around
and start trending down.
Min Op Depth (mm) –
Minimum depth required for the velocity Ultrasonics to be
enabled (switched on)
Min RSSI (Signal) –
Minimum Signal required to provide accurate readings.
Max Signal Spread –
The Spread setting is used to determine how accurate the data
being reported is and if the Starflow QSD is picking up good signals or bad signals; if a
spread higher than 1000 is generated, this generally says that the data being recorded is
unreliable.
