Chapter 4: Calibration
Introduction
There are two different types of calibration for the Interface 5000 potentiostat:
• Instrument DC calibration
• Cable calibration
Calibration can be initiated through 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 Interface 5000 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 Interface 5000 Calibration Cell.
Caution: The standard Interface 5000 calibration calls for an external resistive dummy
cell. Your Interface 5000 was shipped with an Interface 5000 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).
