7.1.3 Slew rate limit
If the process signal has short erroneous high or low peaks, the slew rate limiting can be
used to cut their effects. The slew rate damping limits the maximum change for the output
signal in one second. It should be noted that the slew rate limit damping is recommended
for random noise suppression as it is non-linear.
The slew rate limit can be set through the menu item 5 SLEW RATE. Typical values depend
on the concentration unit but are typically 0.05 % ... 1 % when the concentration is measured
in %.
The following figure gives an example of different slew rate limits.
