68 eDAQ Potentiostats
Chart macros can be used to keep the potential constant for a fixed
period of time, or to drive the reaction backwards by first applying one
potential and then subsequently applying a second potential to perform
an oxidation/reduction cycle. Refer to th
e Chart Software Manual for
more information.
On Macintosh
If you are using a QuadStat, then most constant potential experiments
between ±2.5 V are done by adjusting the internal QuadStat
Applied
Potential, page 57 . If you require applied potentials greater than
±2.5 V, or pulsed waveforms, then you can use the Chart Stimulator
controls as described below.
Chart software can be used to output a constant potential (up to ±10 V)
which the Potentiostat, Picostat, or QuadStat will apply at the working
electrode. These controls are accessed through the Setup menu,

Stimulator (applied potential waveform) controls
Use the Output Voltage… command to
set the baseline potential,
