+ E
This function is used to specify the output damping τ (in seconds) by which changes of the measured
value are dampened.
After a surge in the level or density it takes 5 x τ until the new measured value is reached.

Effect of the output damping; 1: 1: 1: 1: Level change (or density change); 2: 2: 2: 2: measured value

Default
The default depends on the selected "measuring mode" (*05):
• level: 6 s
• limit: 6 s
• density: 60 s
• concentration: 60 s
Selecting the output damping
The best value of the output damping depends on the process conditions. By enlarging the output
damping, the mesured value considerably calmes down bot becomes more slowly at the same time.
In order to dampen the influence of strongly fluctuating surfaces or stirrers, it is advisable to enlarge
the output damping.
On the other hand, if rapid changes of the measured value have to be detected accurately, the
output damping may not be selected to large.
