8.1.3 Signal filter
The sensor is fitted with an internal signal filter function in order to adapt the
measurement flexibly to different measuring requirements. Fluorescence measurements
may have a low signal-to-noise ratio. In addition, there may be disturbances from air
bubbles or contamination for example.
