Introduction
There are three different types of calibration for the Reference 3000 potentiostat:
Instrument DC and AC calibration
Cable calibration
Low I Range DC 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 Manger 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 Reference 3000 has been divided into three sections: Instrument DC and AC
Calibration, cable calibration, and Low I DC Cal. Gain access to all three calibration procedures via the
Utility
selection on the Framework’s
Experiment
drop-down menu.
The Reference 3000 recognizes the type of cable connected to its cell connector. It maintains a separate AC
calibration table for each type of cable. The Gamry Framework will not let you use AC calibration data
recorded using a 60 cm shielded cable for experiments run using a Twisted Pair cable optimized for low-
impedance EIS measurements.
DC and AC Calibration
These two procedures use an external resistive Calibration Cell (see Figure 5-1).
