2.5.1 DAMPING CONTROL

System 1010 provides two different data output filter types, SmartSlew and Time Average (recom-

mended). SmartSlew provides the best combination of data smoothing and quick response to sudden

rate changes. It performs data scatter damping during steady flow periods while maintaining the ability

to respond instantaneously to changing flow rates. SmartSlew values range from [1 to 9]. The default

is [6]. Pick a higher number to slow meter response to a rate change. Time Average integrates the

instantaneous flow rate over a selectable time period. You enter a value (in seconds), which 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.

To edit the default SmartSlew setting:

To access the [SmartSlew] option list press three times.

Scroll the numeric list to the desired choice press

To select Time Average:

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 natural 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).
