i.delta; P.delta; delta; Q.delta(Only with modes CVS
and CPVS)
Difference of two successive mean values of the evaluation
quantities.
Comments
Display of comments if any type of error appeared in the
sweep (e.g.
Ovl. in scan = Overload during sweep; Ovl. in
CDE = Overload during cleaning or deposition; Ovl. in cond.
cycles = Overload during conditioning cycles; No peak
found = no peak found for defined substance; Not used =
peak is not used for calculation).
Note: For CVS and CPVS, two additional evaluation values are dis-
played: V(mL) and Q/Q(0).
Calibration data
Substance
Substance name (see Substance on the Substances tab,
section 5.2).
Calibr.
Calibration techniques std.add. , rec.cc. or smp.cc. (see Cali-
bration on the Specifications tab, section 5.2).
For electroplating bath analytics: Calibration techniques
dt.rec.cc. , dt.cc , mlat , lat rec.rc , sam.rc (see Calibration
techniques with CVS and CPVS, section 6.2).
Y.reg/offset
Evaluation quantity for the sample calculated from the
standard addition curve (for standard addition) or intercept
of the calibration curve (for calibration curves).
Slope
Slope of the standard addition or calibration curve.
Nonlin
Nonlinear factor for nonlinear calibration curves (only dis-
played, if "Nonlinear Regression" was chosen for parame-
ter
Regression technique ).
Corr.Coeff
Corrrelation Coefficient for linear calibration curves (only
displayed, if "Linear Regression" was chosen for parameter
Regression technique ).
Mean deviat.
Calculated mean deviation of the measured values about
the standard addition or calibration curve.
Solutions
No.
Number of Dosing Device used for addition or predose.
Content
Remarks regarding the solution (see Content on the DOSI-
NOS window, section 5.2).
