the Current Carrying Cable which mates with the Current Connector,

and one that senses the cell voltage, called the Sense Cable, which mates

with the Sense Connector.

The standard Cell Cable is 3 m long. The D-connector ends of the cables

are connected to the appropriate ports on the front of the EIS Box.

Always use the knurled screws on this cable to hold the cables in place.

The current-carrying cable contains fuses that

protect the instrument against excessive cell

current.

Running the Framework

Many newer electrochemical applications do not run as an application

within Gamry Instruments' Framework software. This is true of all

applications that use Gamry's Toolkit for instrument control. Gamry's

Framework software is the main application software for performing

routine analysis associated for electrochemical measurements. There

are other software programs such as Resonator that are stand-alone

programs. Programs that you develop using our toolkits will fall into the

stand-alone software category.

The Framework Instrument Manager is useful in organizing the

instruments in the system. The Framework also has a Calibration

program that is used to calibrate instruments connected to the system.

Framework Device Status Bar

By default, the Gamry Framework shows a Device Status Bar under its

main menu (see Figure 4-3). If you do not see the Device Status Bar

when you run the Gamry Framework, it has been disabled in the

Framework Options menu.

Instruments that are connected to the computer appear on this bar. The

round indicator associated with each device shows its status:

Green

The device is available to run experiments

Orange

The device is currently running an experiment

White

The device is connected to the system, but is not usable.

This is generally the result of a mismatch between the

Framework software and the device's firmware. You can

use the Gamry Instrument Manager to fix the mismatch.

The screen capture below shows a Framework screen with three USB

instruments connected.

Figure 4 3 Framework with Three Potentiostats and One Running Test

The Interface 1000 (IFC 01004) in this system is shown with a green

indicator because it is installed and ready to run. The Reference 600

labeled My Ref600 has an orange indicator because it is recording the

EIS spectrum shown on the screen. The Reference 600 labeled Jims

Ref600 has a white indicator, showing it is plugged in but cannot be

used. This is an indication of a version mismatch between Gamry

Instruments Framework software and the instrument's firmware.

Calibration

DC calibration for the EIS Box instrument is sometimes necessary.

Run calibration through the Framework™ software, or directly through

Gamry Instrument Manager (GIM). Gamry recommends calibrating the

instrument at least once per year, or when the quality of your data is in

question. To initiate calibration, take the following steps:

Click the Calibrate in Framework button, located in the Calibration area

of GIM. This launches the appropriate calibration routine for the

instrument selected in GIM. Follow the instructions given in Framework.

See the relevant Calibration Quick Start Guide for additional details.

If there are any failures during calibration, click the Email Results to

Gamry Support button in GIM. One of our support engineers will review

the results and provide appropriate advice.

You run the Instrument Manager by selecting Options/Instrument

Manager... on the Framework Menu.

Calibrate each potentiostat installed in your system. A calibration utility

is provided with the Gamry Framework.

The calibration for the EIS Box is divided into two sections: Instrument

DC Calibration and cable calibration. Gain access to these calibration

procedures via the Utility selection on the Framework's Experiment

drop-down menu.

Calibrate each potentiostat installed in your system. A calibration utility

is provided with the Gamry Framework. Get access to the calibration

procedure via the Utility selection on the Framework's Experiment drop-

down menu.

DC Calibration

This procedure uses an external resistive dummy cell called the 200 Ω

Calibration Cell.

Potentiostat calibration is only required infrequently. Recalibrate your

EIS Box under the following circumstances:

•

It is at least one year since your last calibration.

•

Your instrument has been serviced.

•

You notice breaks or discontinuities in the data curves

recorded with your system.

•

The system is being run in an environment that is very

different from the previous operating environment. For

example, if the EIS Box was calibrated at 15°C and you are

now operating it at 30°C, you should recalibrate.

Connect the Calibration Cell to the appropriately colored banana plugs

on the Cell Cable.

Cell Connections

Cell Cable Overview

The EIS Box has eight channels. Each channel has two Cell Connectors on

the front of the EIS Box. The Current Connections are female 15-pin D-

connectors, and the Sense Connections are male 15-pin D-connectors.
