Optional Test
After the Gamry Framework and Gamry software packages
have been installed, and the potentiostat has been calibrated,
you are ready to use the Framework interface to run
experiments with the Gamry software packages. General
instructions for running experiments are on page 15.
If you bought the EIS300 Electrochemical Impedance
Spectroscopy Software, you can run an EIS test experiment
using Universal Dummy Cell 3 or 4.
This test is not required. However, it is a good idea to run it
to check potentiostat functionality and to become familiar with
the process of running experiments through the Framework
EIS300 “Check300” Test

When the test has concluded, compare your results with
the screenshot (see left).
If the plot in your Framework window is similar to ours,
the potentiostat passed the test.
If the plot in your Framework window is not similar to
ours, try the experiment again with the Universal Dummy
Cell in a Faraday Cage.
If your plot is not similar to ours after running the test
with the Universal Dummy Cell in a Faraday Cage,
contact us.
If your Potentiostat is not authorized for the EIS300 software
package, this experiment will not run. You will receive an
error like the one shown here. This message is similar to
other messages generated when experiments from notauthorized packages are run. See Page 9 to correct the code
entry or your local Gamry representative to purchase the
additional code.

features available in Echem Analyst by manipulating this
sample data.
(A) Sample Potentiostatic EIS data file as it opens
in the Gamry Echem Analyst.
To open a data file, select File > Open from the Echem
Analyst menu bar. The sample data filenames start with
“Sample” and include the name of the type of experiment,
such as “Sample Cyclic Voltammetry.dta”. Figure A is an
example of a data file as it opens.
Some functions available in the Echem Analyst window are
applicable to many types of experiments. For example,
commands in the Tools menu are available to display point
information, change the current convention, and make other
choices that affect how data is displayed. The Common
Tools menu choices, such as Linear Fit, Add Constant E,
and Add Constant I, let you manipulate data.
Other functions, specific to the experiment type, are available
from the menu named for the type of experiment. For
example, when analyzing data gathered with Potentiostatic
EIS, the Impedance menu contains commands for functions
specific to EIS300 experiments.
Similarly, some tabs in the display, such as Experimental
Setup and Hardware Settings, are common to all types of
experiments. Other tabs, such as Bode, Nyquist, and
Randles (the selected Fit model) in Figure B, are specific to
particular types of experiments.
(B) Manipulated form of the same data file — the secondary Y-axis (Phase
Angle) is reversed, data are fitted, axes are formatted, and both the Curve
Selector and Point Information Viewer are open.
After you have used Echem Analyst menu functions to

Reference Information
Procedure for Experiments
The procedure for running any experiment is:
Gamry File Types
Connect the cell cable leads to the appropriate electrodes on
the electrochemical cell. Refer to the table on this page or the
Gamry mouse pad for the color coding of the leads.
The types of files generated or used by Gamry software are
described below.
Select the script you want to run.
To use a standard Gamry script, select it from the application
submenus, such as DC Corrosion or Electrochemical
Impedance, accessible from the Experiment menu.
To use a custom script, select it from the “Scripts” folder
(Experiment > Named Scripts). This folder contains all scripts
(standard and custom), as well as global scripts used by other
experiment script written in Gamry Explain™
experiment control language; in “Scripts” folder
accessed via Framework Experiment menu
experiment results; in “My Gamry Data” folder
Name the .dta output file that will contain the experiment data
generated by the test. This ASCII text file will be created in “My
Gamry Data” (or the new destination you specify using the
Options menu).
experiment results that have been manipulated in
Echem Analyst; in “My Gamry Data” folder
Specify parameter values. When the window used to run a
script opens, the parameter values most recently used for this
script will be displayed. At this point you have several choices.
calibration results; in “My Gamry Data” folder; file
name is “calibration results <SN>.txt”, where
<SN> is the serial number of the controller board
(the board with the green LED)
experiment parameter values; in “Sets” folder
under software installation location
What It Stores
You can edit the parameter values. You can save the new
values to a “.set” file for future use by clicking on Save.
When assigning a name to the saved parameter values, it
is a good idea to include the name of the script or
experiment in the file name.
You can use values stored in an existing .set file by
clicking on Restore. A window will open that contains all
the .set files for all experiment types. Pick a file of values
for this type of experiment.
You can use the Gamry default values for this script by
clicking on Default.
Start the experiment and activate the potentiostat by
clicking on OK in the experiment window. Depending on the
script you selected, one or more messages may be displayed
containing advice for running the experiment.
If any messages are displayed, follow the advice, and then
acknowledge the messages by clicking on OK.
While the experiment is running, plotted data will be displayed.
Messages in the status bar allow you to monitor progress of the
You can cancel the experiment by clicking on F1-Abort (no test
data stored), skip the current stage of the experiment by clicking
on F2-Skip, or temporarily halt the experiment by clicking on
At the conclusion of the experiment, an “Experiment Done”
message is displayed. The message contains instructions for
closing the window used to start the test.
Press the F2 (Skip) button.
General Instructions for Connecting Leads
The leads on Gamry cell cables are color-coded for easy installation.
The meanings of the colors are below. Color codes are also on the
Gamry mouse pad shipped with the potentiostat.
working sense
counter sense
black (long)
floating ground
black (short)
earth ground
blue and green leads – If you have used other manufacturers’
potentiostats and cell cables, you may be puzzled by Gamry’s use of
two leads for working electrodes. The two working electrode leads
make it possible to devise a greater variety of experiments.
However, to do a standard three-electrode potentiostatic experiment,
connect both the green and blue clips to the working electrode (or
clip the green to the blue, and then clip the blue to the electrode).
orange lead – The orange lead is used only in ZRA (zero resistance
ammeter) experiments.
The grounding leads both have black clips. The longer of the two
leads is the floating ground. The shorter lead with a black clip is the
earth ground.
The short lead can be clipped to an independent earth ground. (The
short lead is connected internally to the computer chassis.)

When using a Faraday Cage, connecting both ground leads to the
cage usually results in the lowest noise. However, leave the short
black lead open if the experiment setup is earth grounded. For
example, if the Faraday Cage, electrolyte circulation pump, or a
