The low current boards are coupled with a channel board, so a low current board must
ALWAYS be calibrated with the corresponding channel board.
The board installation can be validated in two steps:
Firstly, it is recommended to calibrate the channel with the calibration tool which is
available in the “Tools” menu of EC-Lab
®
. The procedure is described in 8 and also in the
Technical Note #18.
If a further check is needed, it is possible to validate the boards thanks to the dummy cells
provided with the board(s).
1.3 Software features
In general, any electrochemical experiment is composed of open circuit sequences and/or
galvanic sequences performed while measuring the potential, and/or imposed potential
sequences performed while measuring the current.
Common electrochemical techniques, such as Cyclic Voltammetry (CV), Chronopotentiometry
(CP), etc. are obtained by combination of these elementary sequences. These combinations
appear in EC-Lab as flow-diagrams for easy visual description for the user.
At various points within any experimental sequence, conditional tests can be performed on the
working electrode potential or current, the counter electrode potential, or the external
parameters. These conditional tests force the experiment to go to the next step, to loop to a
previous sequence, or end the sequence or experiment.
The application software package provides useful protocols for general electrochemistry,
corrosion, batteries, super-capacitors and custom applications. Standard graphic functions
such as re-scaling, zoom, linear and log scales are available. Standard processed files can be
created at the user's convenience upon running an experiment for the purpose of real time
display of the experiments in progress. Post processing is also possible using built-in options
to create variables at the user's convenience, such as derivative or integral values, etc. Raw
data and processed data can be exported as standard ASCII text files.
The user can find more information about EC-Lab
software in the software manuals, available
in the “Help” menu of the software.
It is assumed that the user is familiar with Microsoft Windows

and knows how to use the
mouse and keyboard to access the drop-down menus.
