4.3 General/Specific Parameters
Some electrochemical techniques require many different parameters, and this can
cause confusion. For ease of operation, the parameters are divided into two
categories,
General
and
Specific
.
General Parameters
must be set by the user for each experiment, as there are no
standard values for these parameters.
General parameters
always include the
potential range (
Initial E
,
Final E
,
High E
and
Low E
) and the
Sensitivity
(the gain
of the current-to-voltage converter) (Figure 4-2). Other
General Parameters
include
the
Scan Rate
(for linear sweep experiments) and the
Rotation Rate
(for
hydrodynamic and stripping experiments.

Specific Parameters
have default values, which have been chosen to be reasonable
for most conditions. They do not have to be set by the user for each experiment,
although values other than the default values can be entered.
Specific Parameters
typically include the parameters that define the potential wave form (for techniques
other than linear sweep, potential step and time based); for example, the
Amplitude
and
Frequency
of square wave and sinusoidal potentials and the
Sample Width
,
Pulse Width
and
Pulse Period/Drop Time
for pulse experiments (Figure 4-3).
