The potential waveform for
LOGI
is the same as that for
LSV
. For
LOGI
, the output
is the logarithm of the absolute value of the current output. This can linearize portions
of the voltammogram where the current is controlled only by the rate of electron
transfer. Such plots are called Tafel plots, and are used to obtain transfer coefficients
and exchange currents. These are frequently used in corrosion studies (to measure the
corrosion (exchange) current). The log plot can also be used to display a large current
range in a single plot.
CYCLE
has the same waveform as
CV
. However, in
CYCLE
there is no digital data
acquisition, but the analog current-to-voltage converter is connected and the output is
sent to the I
OUT
jack on the back panel of the BAS 100B. This is used when many CV
cycles are required, and the required data storage exceeds the data storage capacity. It
can also be used to condition the working electrode.
