4.4.7 Filter Function

The filter function provides a damping effect to prevent fluctuation within the output current
and display. There are 2 types of filter (fast and slow) each with 10 levels of damping availa-
ble from 0 to 9 with 0 having no damping effect.
The "Fast" filter is used when rapid changes within the varying flow can occur. (In cases of
quick valve shut off the slow filter will take a few seconds to reach zero, while the fast filter
will react immediately).
The "Slow" filter may be used in bad measuring conditions (e.g. in case of
electrical or magnetical interference, earthing problems, air bubbles in the
fluid, hard fluctuating flow, ...).
