Defining regression coefficients
The “Calibration coefficients for calculation of concentration with scattered light” field
serves to select a coefficients set freely (set 0) or a fixed default setting (sets 1 to 3).
Select set 0 when the measuring system must be calibrated (
see “Calibration for dust con-
centration measurement”, page 69
Sets 1 to 3 can be used when the highest precision is not decisive.

The regression coefficients in sets 1 to 3 refer to dusts with an average density
of 2.5 g/cm³, almost spherical particle structure and even dust distribution across the
duct cross-section.
