2. INSTALLATION 

This chapter details how to install, calibrate, and test the LCI. 

2.1. Installation 

2.1.1. Connect Interface Cable to LCI Main Body 

Connect the interface cable (Section 1.2.1) to the LCI main body (Section 1.2.2) and secure the cable to 
the connector by tightening the screws until snug (

do not over tighten

). 

2.1.2. Connect Interface Cable to Potentiostat Cell Interface 

 

 
Connect  the  opposite  end  of the  interface  cable  to the  potentiostat  front panel  cell  cable  connector  and 
secure  the  cable  to  the  connector  by  tightening  the  screws  until  snug  (

do  not  over  tighten

).  The  LCI 

replaces the standard cell cable supplied with the potentiostat/galvanostat. 
 

 

 

2.1.3. Connect Cell Cables to LCI Front Panel 

Connect the four cell cables to the cell interface panel. The cables and panel on the LCI are labeled WE 
(working  lead),  SE  (working-sense  lead),  RE  (reference  lead),  and  CE  (counter  lead).  The  terminating 
colors  on  the  cell  leads  match  those  of  the  standard  cell  cable  (WE=green,  SE=gray,  RE=white,  and 
CE=red). 

2.2. LCI Calibration 

The VersaSTAT LC Low Current Interface is designed to provide ultra-low current measurements beyond 
the  capabilities  and  specifications of  the potentiostat  to which  it  is  attached.  As  such,  calibration  of  the 
potentiostat-LCI  combination  is  required  each  time  it is connected, and it is highly recommended that a 
calibration be performed prior to each use to provide the best accuracy with each use. 
 

2.2.1 Calibration 

The  VersaSTAT  system  was  designed  to  auto-detect  a  configuration  change,  so  after  adding  the  LCI 
option  and  launching  the  software,  the  following  message  will  appear  immediately  upon  starting  the 
software. 

NOTE 

Once  the  LCI  is  connected  and  power  applied  to  the  system,  a  calibration 
will  be  required,  and  the  user  will  be  prompted  when  the  VersaStudio 
software  is  launched  to  perform  the  calibration  prior  to  use.  Please  see 
Section 2.2 for calibration instructions.  

 

NOTE 

Power  off  the  potentiostat  before  connecting  the  LCI.  Connecting  the  LCI 
with  power-on  will  not  allow  the  potentiostat  to  recognize  the  LCI.  Only  at 
boot-up (cycling the power on the potentiostat) will the LCI be recognized.
