Operation Overview
Figure 2-1 shows a "typical" electrochemical test system built around an ECM8 Electrochemical Multiplexer.
Only four cells are shown in this figure, although up to eight cells can be connected simultaneously. The
label on the block marked as a potentiostat is slightly misleading. Most potentiostats can also be used as a
galvanostat or as a ZRA (zero resistance ammeter) in an ECM8 system.
In the description of this figure, keywords will be shown in bold type. These keywords will be defined in
the next section.
