5.7 User-specific calibration
In principle it is possible for the user to make his/her own
calibration. It is, however, advisable to retain the factory
calibration, since this was performed using a 10-item
cali bration procedure.
A user-specific calibration is made using a standard with a
known concentration. This concentration should be equivalent
to that of the water sample. Here it is possible to use e.g.
Spectroquant® CombiCheck standards or ready-to-use standard
solutions (see chapter 5.2).
In the case of differentiated methods, only the simple form is
calibrated, i.e. with the chlorine methods only free chlorine
is calibrated, and the calibration then automatically applies for
the other two variants (total and differentiated).
The following methods cannot be user-specifically calibrated:
