Operate a sequence in Electroplating Bath VA
The sequence to measure with the electroplating modes CVS or
CPVS includes the following steps:
1.
Initial
mixing time
2.
Initial electrode conditioning
a.
Conditioning cycles
(Number of “conditioning cycles” de-
fined in
No. of cycles
on the
Voltammetric
tab of the
EDIT
WORKING METHOD PARAMETERS
window)
b.
Pretreatment
c.
Sweep
(Number of sweeps defined in
No. of sweeps
on the
Voltammetric
tab of the
EDIT WORKING METHOD PA-
RAMETERS
window)
Note: Define the number of these "Initial electrode condition-
ing measurements” on the
Determination
tab of the
EDIT WOR-
KING METHOD PARAMETERS
window. You can either set a fi-
xed number, or put a ”Std.dev.“ as stabilizing border.
3. First Measurement:
a.
Conditioning cycles
(Number of “conditioning cycles” de-
fined in
No. of cycles
on the
Voltammetric
tab of the
EDIT
WORKING METHOD PARAMETERS
window)
b.
Pretreatment
c.
Sweep
(Number of sweeps is defined in
No. of sweeps
,
number of saved sweeps in
Save last .. sweeps
on the
Volt-
ammetric
tab of the
EDIT WORKING METHOD PARAME-
TERS
window)
Note: Instead of repeating sweeps, you can also repeat
the whole Measurement cycle. Define the number of repli-
cations in
No. of replications
on the
Determination
tab of
the
EDIT WORKING METHOD PARAMETERS
window.
Metrohm recommends to set the
No. of replications
on 1,
the
No. of sweeps
on 4 and
Save last .. sweeps
on 2.
4. First Addition:
Add standard or bath solution (is depending on the
Cali-
bration
technique). You can do it either manually or auto-
matically using Dosing Devices. The
Volume
should be de-
fined on the
Substances
tab of the
EDIT WORKING
METHOD PARAMETERS
window.
