Default calibration for
matrix type 2
The factory calibration curve for matrix type 2 was determined by
measurements of typical decaying slurries and can be used for similar
applications after adaptation of the Correction factor setting (see
section 4.2.3).

Influences If there is a low level of total suspended solids (< 2000 mg/l SiO2 or
< 1000 mg/l TSS), the effects of the measurement environment can
simulate a higher content of total suspended solids. The effect of the
measurement environment is minimized by exactly observing the
installation position (see section 3.3.1).
If an optimum installation is not possible due to the structural conditions
at the measuring location (e. g. in narrow pipelines), interference
effects can be compensated by a User calibration (see section 4.2.4).
