The following two graphs illustrate the effect of filtering the same raw data shown above.
Figure 8 shows the effect of using the following filter settings which create the ‘Filtered
Unscaled’ line on the graph.
Slew-Rate + =
Medium
Slew-Rate - =
Light
Filtering Time =
1 second
Applying Filter: Slew Rate + = Light, Slew Rate - = Medium
Filtering Time = 1 Second

Figure 9 shows the effect of the following settings:
Slew-Rate + =
Light
Slew-Rate - =
Light
Filtering Time =
7.5 seconds
Applying Filter: Slew rate + = Light, Slew Rate - = Light
Filtering Time = 7.5 Seconds

Figure 9: Filtering the RAW Signal (2)
In Figure 9 it is clear that the signal at the dry phase of the mix cycle is more stable which is
more advantageous when making the water calibration.
The default filter settings are suitable for many applications. However, to determine the optimal
settings it is advisable to monitor the results during initial commissioning in order to balance
noise reduction with the speed of response.
