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).
