6.2 Calibration techniques with CVS and CPVS
797 VA Computrace – Software
167
With CPVS: Step potential [ read only ; step 1: 0.2 V ]
Displays the potential values, which are defined in
the window edit stripping steps.
Bsln.
Parameters for baseline evaluation (details see
Baseline, section 5.2). Click the button to open
the BASELINE window for the selected substance.
Additive solution
Definition of addition solutions for standard addi-
tion.
No. [ 0...8 ; 0 ]
Number of addition solution used for manual or
automatic addition. For automatic additions, this
number is also the Dosing Device number. If a
mixed standard solution is used, the number of
this solution must be entered for each substance
present in the mixed solution.
Achtung: Dosino 1..3 refer to Dosinos connected
to the 797 VA Computrace. Dosino 4...7 refer to
Dosinos connected to the 846 Dosing Interface (to
MSB 1...4).
Conc. [ > 0 ; 0 ]
Value for concentration of addition solution.
Unit [ fL/L...mL/L ; mL/L ]
Unit for concentration of addition solution.
Volume (mL) [ > 0.01 mL / var ; 0 mL ]
Addition volume. For entering variable addition
volumes, click the
button to open the EDIT VA-
RIED ADDITION
window for the selected substan-
ce (details see
Variable addition, section 5.2). In
this case, var is entered into the field instead of a
fixed value. This field only appears once for soluti-
ons with the same number (mixed standards) and
it is not displayed if
0 is entered as solution num-
ber.
Contamination potential [ -5...5 ; 1.125 V ]
With CVS: If it is activated, the current is readout
for the defined potential during the last sweep (in
anodic direction) of the bath determination.
With CPVS: One of the defined stripping steps
(Voltammetric tab with Calibration technique
"MLAT") can be selected. If it is activated, the cur-
rent is readout for the selected potential during
the last sweep (in anodic direction) of the bath de-
termination.
The Contamination potential correlates with the
concentration of organic degradation products in
the electroplating bath.
