7.7 Function "echo quality" (056)
The echo quality is the benchmark for measurement reliability. It describes the amount of reflected
energy and depends primarily on the following conditions:
• Dielectric constant of the medium
•probe type
• Distance between sensor and product
Low values increase the probability that the echo is lost through a change in measurement condi-
tions, e.g. angel s of repose or large measuring distance.
7.8 Function "offset" (057)
This function corrects the measured level by a constant value. The entered value is added to the
measured level.
7.9 Function "output damping" (058)
Influences the time an output requires to react to a sudden level jump (63% of steady state). A high
value attenuates, for example, the influences of rapid changes on the measured variable.
User input:
0...255 s
The default value depends on the selected application parameter "process cond." (004).
