Step-by-Step Software Authorization for a MultEchem System

Posted on 7 July 2016

MultEchem systems allow multiple instruments to share a single software license and be run from a single computer. The system utilizes a USB dongle to activate the software license across all instruments.

IC8 Does not boot with dongle inserted

Posted on 7 July 2016

It is well documented that certain USB storage devices can prevent a computer from properly booting up. The USB dongle for your MultEchem IC8 system can cause this problem under certain conditions. To prevent it, either unplug the device before booting the computer or modify the BIOS settings for “booting from a USB device” so that the dongle is ignored while the computer is loading.

What is an Authorization Code?

Posted on 7 July 2016

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.

Should I choose "vs. Eref" or "vs. Eoc" for EIS on coatings?

Posted by Gamry on 7 July 2016

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.

Basic Explanation of Overloads

Posted on 7 July 2016

During acquisition in the Framework software users will sometimes observe overloads (red or orange data points) indicating that the instrument is in an undesirable state.  When an overload occurs one of 5 indicators will switch on, showing a red or orange box at the bottom of the experiment runner window with a message indicating which overload state has happened.  At the same time the data points will turn red or orange for the overloaded points.  Here is a basic explanation of the different types of overloads:

Stuck At Autoranging - PCI4/Series G

Posted on 7 July 2016

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.

Using the Multiplexer Setup Script

Posted on 7 July 2016

In addition to controlling up to eight electrochemical cells in sequence, the ECM8 also has local potentiostats on each channel.  These are utilized in the standard Multiplexer experiments of Potentiostatic and Galvanic Corrosion to appropriately control the potential of the inactive cells.  These channel settings can be individually modified by using the Multiplexer Setup script in Experiment / Utilities…

The Setup screen is split into 3 sections:  Local Potentiostat Control, Active Cell, and Active Mode.  The local potentiostat for each channel can be set individually with a maximum potential of +/- 5V.  Set this to OFF for an open inactive cell, and set it to ON with a voltage of 0 V for a short circuited working and counter electrode.

The Active cell section turns on one channel of the Multiplexer.  This is necessary if you want to run a standard, individual cell experiment and do not want to disconnect the Multiplexer.  The amber channel light on the front of the Multiplexer will light up for the channel you select, and this channel will stay active until you change the setting or run one of the Multiplexed DC Corrosion experiments.  The Multiplexed DC Corrosion experiments handle all switching of the active cell automatically.

Active mode specifies the operation mode for the active cell.  In NORMAL mode the potential is controlled between the working sense and reference leads.  In ZRA mode the potential is controlled between the working sense and counter sense leads.

Scripts from Multiplexed DC Corrosion will automatically control these 3 sets of parameters so that the desired experimental conditions are applied (e.g. multiplexed galvanic corrosion will set each inactive channel to short circuit, change the active cell to take measurements, and utilize ZRA mode on the active cell).
