Generally, a longer measuring path (10 mm (0.39 in)) is recommended for measuring lower
absorption values and thus for low-viscosity or watery liquids.
Higher absorption values, on the other hand, can be measured with a shorter measuring path
(5 mm (0.2 in)). This path length is thus suitable for measuring liquids with a high solids
content (e.g. sludges) or highly absorbing, dark media.
Measuring path Measuring range (absorption of medium)
5 mm (0.2 in) 0 to 10 OD
10 mm (0.39 in) 0 to 5 OD
Configuring the unit
The most common units are stored for each application (e.g. absorption, formazine or kaolin)
and can be selected in the data record. (For example, "Sludge" application; units: g/l, mg/l,
ppm).
There is also the additional option of selecting "User unit" as the unit. Here, any unit name or a
character string can be assigned to the "Basic unit" (e.g. OD for absorption). The system can be
calibrated to this unit.
1-point and multipoint calibration
• Before the calibration, clean the sensor's measuring gap and remove fouling and deposit
buildup.
• During calibration, immerse the sensor in the medium in such a way that the two
measuring gaps are completely filled with the medium. All air bubbles and air pockets must
be cleaned out of the measuring gap during immersion.
• In the calibration table, the actual values can be edited as well as the set points (right and
left columns).
• Additional pairs of calibration values (actual values and set points) can be added, if
required, even without measurement in a medium.
• Lines interpolate between the calibration points.
1-point calibration to the current operating point is generally sufficient since the zero point of
the sensor is precalibrated at the factory for all available applications.
