A Gamry PC4 can often outlive the computer into which it was first installed. PC4 potentisotats require a computer with two adjacent ISA slots. They are not plug-and-play equipment and require some settings tweaking to get them up and running. Here are two common problems that are received when launching the Gamry Framework for the first time after installation:
Technical Support Resources
We will no longer offer support or repairs for Series G potentiostats at the end of 2019. In the interim if any of these instruments returned for repairs are unable to be repaired, we may be able to offer some trade-in value towards a new potentiostat. Please contact our Sales Department to discuss 'Trade-In' offers available to upgrade to the latest instrument.
Effective May 1, 2016 we will no longer offer support or repairs on our PCI4 potentiostats. Please contact our Sales Department to discuss current 'Trade-In' offers available to upgrade to the latest instrument.

A number of users bring potentiostats into the field and need a reliable source of short term power for experiments. All of our USB potentiostats run from 120V AC wall outlets, but with varying power requirements.
An AC power inverter is required to run the potentiostat from automotive or marine batteries. Gamry has not tested specific inverter products, but generally a unit that can supply 750 watts continuous will be able to run the instrument. Products by Tripp-Lite, such as those from the POWERVERTER Series are designed for heavy-duty operation connecting directly to an automotive battery. Marine batteries, however, are designed for deep cycle operation and are better suited for longer use of the potentiostat in the field. Always use the power transformer block and cable that came with your USB instrument. Damage could result from connecting any power source directly to the back of the potentiostat.
Authorization Codes activate your Gamry Software to work with your potentiostat. Each of the software packages has a package name (e.g. “DC105” for DC Corrosion Techniques) and a 10-digit Authorization Code that is linked to the serial number of your instrument.
We have seen several examples where a customer has recorded an open circuit voltage of 3, 4, or even 5 volts when running EIS on a coated sample. The Eoc values that were recorded in these experiments are probably not real Eoc readings. For very, very good coatings, such as the ones that these researchers were studying, we recommended that the potentiostatic EIS measurement be done at a potential vs. Eref, not vs. Eoc. The Eoc values are often not related to the coating or to the substrate: They are a function of the length of time the potentiostat has been connected to the cell.
The “Copy to clipboard” button is located on the toolbar of the Chart tab when your data file is displayed in Echem Analyst. This button gives you the option to copy a Bitmap, Metafile, or raw data directly to the Windows Clipboard. It can then be pasted into any other program. The Bitmap option will copy the data as displayed in Echem Analyst, meaning that it will be a replica of the current view of the data complete with any overlays, fits, or modifications of the visual style of the plot. Using the “As Text (data only)” button will copy the X and Y values of the currently displayed data, fits, and overlays as a table that can be directly pasted into a cell-based spreadsheet application. By overlaying multiple data files you can use the Copy As Text feature to batch-export a number of data files in one fell swoop.
The signal optimization step of the OptiEIS experiments can take (at a minimum) as long as 2 cycles of the minimum frequency entered during setup. During this step the current measurement range of the potentiostat is selected based on the amplitude of the signal. The "Max Current" box of the setup screen determines the initial current measurement range used during optimization. The optimization can take much longer, by multiple attempts at signal optimization, if the Max Current is too low, as it has to switch to the next range up and reattempt. The best method is to make an educated guess of the maximum current value with some knowledge of the impedance of the sample.
Microsoft is Ending Support for Windows 7
Microsoft will discontinue support for Windows 7 on January 14, 2020 which means Gamry will also be discontinuing support for Windows 7. If you are upgrading to Windows 10, like many companies and institutions, you need to be running Version 7 of our software. Please note that only USB and Ethernet-based instruments can run in Version 7. Eligible users can download the latest version of our software through our online Client Portal.
If you haven’t already registered your instrument, you can do so through the Client Portal.
Please email Technical Support if you have any questions regarding this transition. Please be sure to include your instrument model and serial number when contacting us.
