Damping function(OFF). the meter follows the trend

Damping mode based on time (fro 0.2s to 1000s)
The measure is averaged over a number of
samples determined by the value assigned to the
dampening function. When the damping parameter
is expressed in seconds, the filter works damping
the measurement noise and sudden change of
flow rate. Increasing the parameter of damping
increases the stability of the measurement.

This section of manual is extremely important because the correct setting of the filters allows to obtain a proper response
of the instrument to the measured flow rate and the specific requirements of use; as a general rule, consider that, starting
from Damping = OFF (no filter applied to the measure), successive values, introduce increasing damping. The following
diagrams show the instrument’s response to changes in flow rate from 0 to 100%, using the different settings of the
damping function.
The SMART is an adaptive filter that adapts automatically to most of the processes (recommended value), making the
response of the meter very ready to fast changes of flow and at the same time extremely precise and stable for slow
variations. It may be convenient to use a constant damping filter time, where there is a pulsating flow (for example
generated by peristaltic pumps). With longer times you get a mean value stable, while with short times the measure will
closely follow the flow pulses, but consequently more unstable. NOTE: If the rechargeable battery is active, the damping
could be set only in “SMART”.
