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.

OptiEIS: Signal optimization takes too long or chooses wrong range

Posted by Aaron on November 9, 2011

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.

Installation of a MultEchem System

Posted by gamry on October 24, 2011

MultEchem systems allow multiple instruments to share a single software license on a single computer.  The system utilizes a USB dongle to activate the software license across all instruments.  For all Framework versions before 5.63 one must select “MultEchem” from the Select Features page of the installation program to install the driver for the USB dongle.  This driver is installed automatically in current versions.

Manually changing the Port number for your ECM8 or TDC4

Posted by gamry on October 24, 2011

When installing a second ECM8, or switching to a USB-to-Serial adapter for your ECM8 or TDC4, it is necessary to manually change the Port number in the Gamry.INI file. The correct Port number allows the Framework Software to communicate properly with the Gamry Hardware device. The INI file is accessible from the Windows Start Menu under Gamry / Framework / Gamry.ini. The file will open in your default text editor program.

Vac too small

Posted by gamry on July 28, 2011

EIS logo2There are several possible reasons that this message will appear during an EIS scan. The first thing to check is that all of your cell connections are appropriate. If the error continues to appear one should run a full calibration of the system. During the calibration the performance of the EIS components are checked. Depending on the results of the calibration, we can determine if the problem may be cable related or if a repair of the instrument is required. Please email your Calibration Results file (generated during calibration and stored as a .txt file in the My Gamry Data folder) to Gamry by using the Technical Support Form.

Stuck At Autoranging – PCI4/Series G

Posted by gamry on July 28, 2011

The symptom is that at the start of the experiment no data acquisition begins and the runner window displays “Autoranging” in the lower left hand corner. This applies only to PCI potentiostats installed inside a desktop computer. Verify that the 4-pin power cables are connected to the control board and potentiostat board inside the computer. The instrument will still be properly recognized by the computer without the power cables connected but no signal generation or data acquisition can occur without the power.

Reply Timeout Error

Posted by gamry on July 28, 2011

The “Reply Timeout” error means that the Gamry Software has lost hardware communication with the instrument. The most common reason for this is the resetting of the USB communication chip inside the instrument, caused by a static discharge. To reset the instrument switch it off AND unplug the USB cable from the back. Ensure that the instrument is being used in an environment that meets the operating conditions laid out in the hardware manual. If it is possible, ground the chassis of the instrument as well. Furthermore, discharge yourself before handling the instrument and cell cables.

usb cableAnother reason for receiving the “Reply Timeout” error is a communication interruption due to the use of excessively long USB cables and/or passive external USB hubs. The Reference Family instruments are rated and tested with a 6’ USB cable. Longer cables can work, but the quality of USB cables varies quite a bit and the additional length or a poor quality cable will cause issues with instrument communication. Likewise, connecting through a USB hub that is not powered can cause the same problems. For the best performance the instrument should be used with the provided 6’ USB cable, or with active USB cables and powered USB hubs, and high data rate devices (such as external hard drives and video devices) should not be on the same USB hub as the instrument.
