4.3.2 Smoothing
The smoothing of a parameter may be necessary if the measurement signal is very unsteady and the output
concentrations vary greatly. This can happen if the measuring medium is inhomogeneous or in motion. The
goal is to eliminate spikes in the course and to let the measured values increase only slowly. The setting of the
smoothing (in %) denes the maximum deviation of the current measured value from the previous measured
value.
The function can be activated for each measured value on the Tribox, whereby a maximum signal change of 1
to 999 percent of the previous measured value can be congured.
Caution:
• If the current (averaged, scaled) measured value is NaN*/range, then no smoothing is performed and the
result is also NaN.
• If the current measured value is 0, then the 0 is replaced by the previous (averaged, scaled and smoothed)
measured value.
• If the parameter settings are changed, a recalculation is then carried out on the basis of the rst measured
value after the change.
* NaN = Not a Number.
