2.5.1 DAMPING CONTROL
System 1010 provides two different data output filter types, Time Average and SmartSlew™.
Time Average (recommended) integrates the instantaneous flow rate over a selectable time
period. Use the Time Average function when stability in flow reading is essential. A value
entered (in seconds) sets the time it takes the meter to respond to a rate change. The default
is 10 seconds. Enter any amount of time up to 60 seconds maximum.
SmartSlew™ performs data scatter damping during steady flow periods while maintaining
the ability to respond to changing flow rates. SmartSlew™ values range from [1 to 9]. Pick a
higher number to slow meter response to a rate change.
To select Time Average (default):
To access the [Damping Control] option list press
To move the cursor down to [Time Average] press
To enable Time Average entry press
Use the numeric keys to type the new Time Average setting.
To register the new value press
To edit the SmartSlew™ setting:
To access the [SmartSlew] option list press three times.
Scroll the numeric list to the desired choice by pressing
To register the new value press
2.5.2 DEADBAND CONTROL
Use Deadband Control to instruct the meter to report zero flow if the flow rate falls below a
specified level (usually a very low rate). It will prevent the possibility of data scatter (a natu-
ral result of digital computation) from causing false totalizer accumulation during long non-
flowing periods. Inspect the actual data scatter during zero flow conditions to find the proper
deadband setting for your application.
To edit the default setting (0.000):
To enable numeric entry press
Use the numeric keys to type in the desired rate (using selected flow rate units).

2.5.3 MEMORY/FAULT SET
Certain situations (e.g., an empty pipe or excessive aeration) will interrupt data production.
Use Memory/Fault Set to select the meter response to such an interruption. The Fault setting
