Chapter 5: Calibration
Introduction
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.

DC Calibration
This procedure uses an external resistive dummy cell called the 200
Ω
Calibration Cell.
Caution:
The standard EIS Box calibration calls for an external resistive dummy cell.
Your EIS Box was shipped with a 200
Ω
Calibration Cell, which includes a 200 Ω , 0.05% accurate resistor.
After calibration, please place this dummy cell in a safe place where you can find it if your unit requires
recalibration.
If you do need to recalibrate and you cannot find your calibration cell, you can perform DC Calibration
using a different 200
Ω resistor. Its power-rating is unimportant. Some performance checks in the
calibration process may fail if the resistors inaccuracy exceeds 0.2% (4 Ω).
