The data of the last standard or sample addition and subtraction to
have been carried out can be called up with <ADD.DATA> provided
that the measurement type has been set to ' std.add ' or ' smpl.add ' un-
der PARAMETER Conc/measuring type . The data are still present
even if the last result has been replaced by ' ------ ' in the measured
value display because the addition run was terminated prematurely.
However, the production of a report of the last result is not possible
then.
The term 'addition' is used below to include both standard and sample
addition and subtraction.
ion type:
The analyte defined for the addition under
PARAMETER Conc/ion pa-
rameters is shown here.
meas.type:
Whether the shown data come from an addition or subtraction run is
shown here.
electr.id
If an electrode Id has been entered or selected before the calibration
under PARAMETER Conc/measuring parameters/electr.id then it
will be shown here.
Later alterations of the parameters
ion and electr.id have no effects
on the display of the addition data.
