28 eDAQ Potentiostats
Check that all connectors are firmly attached. Loose connectors can
cause erratic behaviour, or may cause the Dual Picostat to fail to work.
The Dual Picostat typically uses two, three, or four
e-corder
input
channels during normal operation, depending on its configuration:
• when used as a single channel potentiostat, or when used as a
four-electrode potentiostat, there are two signals (current and
potential). Connect Iout 1(current signal) to e-corder Input 1, and
Eout 1 (potential signal) to
e-corder
Input 2, Table 3–2 .
• when using the Dual Picostat as two potentiostats with two
separate samples, there are two current signals (Iout 1 and Iout 2)
and two potential signals (Eout 1 and Eout 2). Connect the Picostat
as shown in
Table 3–3 .
• when used as a bipotentiostat, there are two current signals
(Iout 1 and Iout 2) and one potential signal (Eout 1). Connect the
Picostat as shown in
Table 3–3 .
Note that it is also possible when using Chart software to connect the
Dual Picostat to other
e-corder
input channels but in these cases the
discussion that follows would change accordingly.
