– Use the regression function of the measuring system (use without measured value
computer). In this case, the correlation to the extinction has to be determined. To do
this, calculate the regression coefficients cc2, cc1 and cc0 to be entered in the mea-
suring system from K2, K1, K0.
Using (2) in (1), the result is as follows:
Using (3), the result is as follows:
Now enter the regression coefficients cc2, cc1 and cc0 determined in directory “Configu-
ration/Application parameters” (
see “SOPAS ET menu: DH C200/Configuration/Application
parameter (example)”, page 64 ) (set sender/receiver unit to “Maintenance” state and
enter the Level 1 password. Reset the sender/receiver unit back to “Measurement” state
afterwards.)
