INTRODUCTION 
1.1. About This Manual 
This manual covers the installation and use of the VersaSTAT LC Low Current Interface (Figure 1) option 
for the VersaSTAT series and some PARSTAT series of potentiostats/galvanostats. The VersaSTAT LC 
is also referred to as the LCI option. 
 
This  manual  does  not  discuss  software  installation  or  operation  outside  of  the  calibration  procedure 
(Section 2.2). For software operation, please refer to the VersaStudio™ operation manual. 
 
Chapter 2 describes how to properly install, calibrate, and test the LCI option.
