The following filter settings are available:
Measured value filter Description
Weak Low filtering, high sensitivity, fast response to changes (2 seconds)
Normal (default) Medium filtering, 10-second response time
Strong Strong filtering, low sensitivity, slow response to changes (25 seconds)
Specialist This menu is designed for the Hauser Service Department.

Air bubble trap
In addition to the measured value filter, the sensor also features a filter function to suppress
the measured errors caused by air bubbles.
Air bubbles cause the measured value to increase in liquids with low turbidity (with a low
solids content). The filter function cuts off these measured value peaks by outputting the
minimum value within a specified time interval. This time interval can be configured using a
numerical value from 0 to 180 seconds. The bubble suppression filter is disabled (value 0) in
the default configuration.
It is not recommended to enable the bubble suppression filter in liquids with a high level of
turbidity (with a high solids content). Air bubbles do not cause the measured value to increase
in media of this type and thus cannot be eliminated with the minimum filter.
Both signal filters (measured value filter and bubble suppression filter) can be configured
directly in the calibration menu of the relevant data record.
8.1.5 Calibration kit
The calibration kit can be used to check the functional integrity of the sensor.
Two different calibration kits are available ("Reference tool" and "Solid state reference"):
Reference tool
During factory calibration, the reference tool is matched specifically to a special sensor and
can be used only with this sensor. Therefore, the reference tool and the sensor are
permanently assigned (married) to one another.
Solid state reference, CUS50D kit
The CUS50D kit, which is available as an accessory, is not assigned to a specific sensor but
rather can be used for any CUS50D sensor. Its tolerance range is thus greater.
Measuring path length Reference tool and solid state reference
5 mm 0.5 AU (1 OD)
10 mm 1 AU (1 OD)
Before checking the sensor, the sensor head with the two measuring gaps must be carefully
cleaned and then dried.
