quoted are approximate

Unity gain
"cell"
When
in
doubt as to the
stability of
the cell polarization,
start with
a low
bandwidth,
e.g.
type J for the
potentiostat,
and increase the
bandwidth for
successive
measurements
until an unstable
point (if any)
is reached. Then
reduce
the bandwidth
sufficiently
to achieve
stable operation.
For particularly
unstable
systems,
of course,
you may have
to reduce the
bandwidth well
below the stable
operating
point and start
again.
