Enter the calibration coefficients
There are two possibilities:
– Direct input of K2, K1, K0 into a measurement computer.
– Use of the regression function of the measurement system (no measurement com-
puter necessary).
In this case the correlation to the extinctionhas to be determined. To do so, the
regression coefficients cc2, cc1, cc0 to be entered in the FW100 have to be calcu-
lated from K2, K1, K0.
By using (2) in (1), the result is as follows:
Using (3), the result is as follows:
Enter then the determined regression coefficients in the the "Configuration / Appli-
cation parameters" directory.
b
Set the sender/receiver unit to "Measurement" mode.
NOTICE:
The coefficient set entered in the sender/receiver unit and measuring
range entered in the MCU may not be changed in this case any more. If
the LCD option is used, the dust concentration is displayed in mg/m³ as
an uncalibrated value.
This method allows changing the parameters for the selected measuring
range as desired.
