The measurement display is
shown.

Insert the cell with the respective
standard.
The absorbance is measured. The
result of the first single measure-
ment is displayed.
8
If necessary, make additional sin-
gle measurements for the median
value formation with

If the zero standard concentration (reagent blank value E0) is not
measured and stored, the photometer calculates the calibration
line without this value. If the function
User-defined blank value
(in
the
Concentration
/
Setup
menu) is activated for measuring with
this method, the value for a0 is determined and replaces the cal-
culated axis intercept from the programming of the method (a0
see Page 64).

Repeat the steps 6 to 9 until all
input fields in the
Absorbance
col-
umn are filled out.
