3.5.2 Selecting the Measuring mode
Specify the following data in the Measuring mode setting

Matrix type (1 or 2)
 Display (TSS or SiO2)
 Unit (mg/l or %)
Determining the matrix
type
Determine the matrix type for your application with the aid of the follow-
ing table:
Measurement in mg/l
TSS (total suspended
solids)
Measurement in mg/l
SiO2 (silicon dioxide)

If the matrix type for a measuring medium cannot be deter-
mined using this table, select matrix type 1 and then carry
out a user calibration (see section 4.2.4). If the graph of the
value pairs corresponds to one of the forms 1 to 3 (see sec-
tion 4.2.4), matrix type 1 is suitable. If the graph of the value
pairs corresponds to form 4, matrix type 2 must be
selected.
