viva 1.1 (for process analysis)
Auxiliary electrode
Standard electrode of the Auxiliary electrode type, which cannot be
deleted.
'Electrode name'
Electrode of the Auxiliary electrode type from the electrode table.
Electrode check
The electrode test for the reference and auxiliary electrodes can be acti-
vated and deactivated only in the START command (see "Electrode test
for VA measuring commands", page 579).
Stirrer
Stirring rate
Number of revolutions per minute of the stirrer.
Input range
0 - 3,000 min
⁻¹ (Increment: 100)
Default value
2,500 min
⁻¹

The parameters for the pretreatment can be set on this tab.
Stirring time
Waiting time during which the solution is stirred in the measuring cell.
Input range

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 reaction products of electrode redox processes.
