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 1 s. The slew rate limit damping is recommended for random noise suppression as it is non-linear.

Select Slew rate to set the slew rate limit. Typical values depend on the concentration unit but are typically 0.05 % to 1 % when the concentration is measured in %.

Figure 1. Slew rate damping. The following figure gives an example of different slew rate limits.
To avoid overdamping, do not make the signal insensitive.
