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 available 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, ...).
