Introduction
The Keithley Instruments Models 2450-EC, 2460-EC, and 2461-EC Potentiostat/Galvanostat systems
are alternatives to traditional electrochemistry potentiostats and galvanostats. Your instrument
features a full-color, high-resolution touchscreen, which lets you configure tests and immediately view
results.
The following electrochemistry test applications are loaded in the memory of your instrument:
• Cyclic Voltammetry: Potential is swept at a user-programmable scan rate between two to four
defined potential vertices, and the resulting current is measured at specified intervals during the
sweep.
• Open Circuit Potential: Measures the cell potential difference between two electrodes with high
input impedance as a function of time.
• Potential Pulse and Square Wave with Current Measure: Sources potential at programmable
peak and base levels. The resulting current at the pulse peak level is recorded.
• Current Pulse and Square Wave with Potential Measure: Sources current at programmable
peak and base levels. The resulting potential at the pulse peak level is recorded.
• Chronoamperometry: Potential is stepped to a programmed value and the resulting current is
measured as a function of time.
• Chronopotentiometry: Current is stepped to a programmed value and the resulting potential is
measured as a function of time.
This kit is not intended to be used with a SMU interlock enabled. To prevent electric shock
and possible damage to the test cable assembly or test setup, do not activate the Keithley
Instruments 2450, 2460, or 2461 interlock.
When the interlock is not engaged on the 2450, 2460, or 2461 the nominal output is limited to
±42 V. However, review the "Safety Precautions" section of this document to ensure
responsible operation.
