Chapter 3 — The Picostat 29
The Back Panel
The back panel of the Picostat is shown in Figure 3–3 .
E Out, I Out and E In Connectors
The Picostat back panel has three BNC connectors labelled E Out,
I Out, and E In. The E In is connected to the Output of the
e-corder ,
usually Output – is used. If you need to reverse the polarity of the
Picostat use
e-corder .
The Picostat provides two signals: the potential signal (E Out) indicating
the potential difference between the working and reference electrodes;
and the current signal (I Out) indicating the current flow between the
working and auxiliary electrodes.
For most situations I Out is connected to e-corder input channel 1, and
E Out to e-corder input channel 2. However, when you are using Chart
software and recording data from various sources on more that just two
channels you may want to connect the Picostat to other
e-corder input
channels.
