Cleaning potential (V) [ -5...+5 V ; -0.1 V ]
Voltage applied to the electrodes during the Cleaning time .
Cleaning time (s) [ 0...80600 s ; 0 s ]
Time during which the Cleaning potential is applied to the
electrodes.
Deposition potential (V) [ -5...+5 V ; -0.9 V ]
Voltage applied to the electrodes during the Deposition time .
Deposition time (s) [ 0...80600 s ; 60 s ]
Time during which the Deposition potential is applied to the
electrodes.
Equilibration time (s) [ 0...80600 s ; 5 s ]
Waiting time before starting the sweep; with start potential
applied to the electrodes. If the checkbox
Hydrodynamic
(measurement) is not checked, the stirrer is switched off dur-
ing that time.
Achtung: In the CVS and CPVS mode, no deposition is pos-
sible, and an own Equilibration potential can be defined (see
Pretreatment with CVS and CPVS). With CPVS, it is part of the
sweep.
Stand-by potential
The stand-by potential can be applied to the electrodes at the
end of the measurement. It remains in force until it is switched off
manually in the
COMPUTRACE CONTROL window or until a new
voltage is applied to the electrodes in the next measurement.
Cell off after measurement [ on, off ; on ]
Enable/disable the switching off of the voltage applied to the
electrodes after measurement.
Stand-by potential (V) [ -5...+5 V ; -0.1 V ]
Voltage to be applied to the electrodes after measurement if
the
Cell off after measurement box is not activated.
Note: If Cell off after measurement is not checked, and you
want to remove any electrode cable, the Stand-by potential
must be turned off by clicking the button on the
COMPUTRACE CONTROL window.
