Chapter 3 — The Picostat 33
The Picostat uses two e-corder input channels during normal operation.
The remainder of this chapter assumes that you have connected the
current signal to
e-corder Input Channel 1 and the potential signal to
e-corder Input Channel 2. (It is possible when using Chart or Scope
software to connect the Picostat to other e-corder input channels in
which case the description that follows would change accordingly).
When using EChem software, Channel 1 is always set to be the current
signal (the I channel), and Channel 2 is automatically set to be the
potential signal (the E channel). Thus when using EChem software you
must always connect the current signal (I Out) to Input Channel 1, and
the potential signal (E Out) to Input Channel 2, of the e-corder .
Channel 2 normally displays the applied potential and its settings are
controlled using the standard Input Amplifier dialog box, described in
the
Chart and Scope Software Manuals which are installed as pdf files
in the eDAQ Documentation folder on your computer hard disk.
First Use
After you have installed the software, connected the e-corder and
computer as described in the booklet that is supplied with the e-corder
system, and connected the Picostat as described above, you are ready
to begin.
When the e-corder is turned on, and Chart software started, the Picostat
Online indicator (green) should light. Touch the body of the Picostat or
e-corder (to discharge any static charge that you may have
accumulated), then attach the 100 MΩ test resistor (supplied with the
Picostat) to the electrode leads so that the Working electrode lead is
connected to one end of the resistor, and Reference and Auxiliary
electrode leads to the other).
From the Channel 1 Function pop-up menu, select the ‘Picostat’
command, which accesses the Picostat control window,
Figure 3–7 ,
Figure 3–8 , or Figure 3–9 .
The Picostat control window allows you to preview the current signal
without actually recording the signal to the computer hard disk. (If the
menu says ‘Input Amplifier’ instead of ‘Picostat’ then the software has
