Selecting YES will reset the system to the basic parameter settings.
The default settings will be restored and all customer modifications
will be eliminated (system general reset).
Service code
Entering a special code provides additional system settings options. These options
may include capabilities, such as modifying the beam angle or medium sound of the
velocity sensor, transmit voltages, or special adjustments regarding the transmitter’s
crystal drive. These settings may be modified only by ADS personnel during start-up
activities because they require comprehensive knowledge of the equipment and
should not require adjustment during standard use.
Damping
This menu enables the user to adjust the display and analog output damping between
20 and 600 seconds. A 0 to 100 percent increase in the calculated volume requires
the designated time to pass on either the display or the output.
Based on the damping setting, the FlowShark Pulse reading will fall to 0 if this period
expires without an accurate depth/height measurement.
Damping, Example 1: Damping 30 seconds, jump from 0 l/s to 100 l/s (=100 %) –
unit requires 30 seconds to run from 0 l/s to 100 l/s.
Damping, Example 2: Damping 30 seconds, jump from 80 l/s to 100 l/s (=20 %) –
unit requires 6 seconds to run from 80 l/s to 100 l/s.
Constancy
The constancy parameter represents the period during which the FlowShark Pulse
will retain and output (via Analog Output) the last valid reading before registering
zero (e.g., due to a temporary sensor obstruction).
