eDAQ Picostat, User Manual

Page: 78 / 122

74 eDAQ Potentiostats
and the Curve Fit extension are installed.
Remember to operate the Potentiostat or Picostat at full bandwidth (that
is do not use the low-pass filters if possible) or else your results may be
dominated by the low-pass filter response!
Chronoamperometry with Scope
For chronoamperometric measurements, where you need to overlay the
results of successive experiments, Scope will generally be the program
of choice.
The total length of the experiment is chosen in the Time Base panel. Up
to 2560 data points can be collected in a period of up to 128 s long.
You should normally use the full bandwidth of the Potentiostat or
Picostat (that is, do not use the low-pass filters) or the response of the
