Hydrodynamic measurement
on | off (Default value: on)
If this check box is activated, then stirring will continue during the sweep.
Only editable for Sensor type = RDE, otherwise disabled.
5.5.2.3.2.3 CVS - Pretreatment
Tab: Method ▶ CVS ▶ Properties... ▶ Pre-treatment
Command name
Name of the command.
Entry 25 characters
The parameters for the pretreatment can be set on this tab.
Stirring time
Waiting time after deactivation of the deaeration, during which the stirrer
is activated.
Input range 0.0 - 9,999.9 s (Increment: 0.1)
Default value 5.0 s
Potential 1
Potential that is applied to the electrodes during the Waiting time 1.
This potential can be used e.g. as cleaning potential for the electrochemi-
cal cleaning of solid-state electrode surfaces that have been contaminated
with products of electrode redox processes.
Input range -5.000 - 5.000 V (Increment: 0.001)
Selection off
Default value off
Waiting time 1
Waiting time during which the Potential 1 potential is applied to the
electrodes.
Only editable for Potential 1 ≠ off, otherwise inactive.
Input range 0.0 - 9,999.9 s (Increment: 0.1)
Default value 0.0 s
Potential 2
Potential that is applied to the electrodes during the Waiting time 2.
This potential can be used e.g. as deposition potential for the electro-
chemical preconcentration in Inverse Voltammetry.
Input range -5.000 - 5.000 V (Increment: 0.001)
