Starting Data Logging 

1.  Establish  communications  between  the  computer  and  Acuity  LS  device

.    Refer  to  “Establishing 

Communication

 above. 

2.  Select 

“Start Data Logging”.   

3. 

Synchronize clock.  Refer to “Clock Synchronization” above. 

4.  Set the sampling interval.  Select "Yes

" to keep current sampling interval, or select “No” and enter 

a  new  sampling  interval  (Figure  10

,  left).      Once  new  sampling  interval  is  entered,  select  “OK” 

(Figure 10, right).

5.  Use  the  Installation  Description  window  to  enter  aircraft/asset,  Acuity  LS  device,  and  LSP 

information (Figure 11).  

CAUTION: 

DO  NOT  use  any  “,”  or  carriage  return  (enter  key)  characters  in  the  provided  text 

boxes. 

 

The Aircraft/Asset window can be used to enter specific information and notes about the 
aircraft, asset, or structure being monitored. 

 

The  Acuity  LS  device  window  can  be  used  to  enter  specific  LSP  or  other  information 
about the materials and condition of the LSP, such as coating information if used. 

 

Within the Acuity LS device window, answer the question, "Coating applied to gold IDE?". 
The default answer is "No".  If a coating is applied to the gold sensor then "Yes" can be 
selected from the drop-down menu. 

i.  For  "No"  coating  applied  to  the  gold  IDE,  the  high  frequency  gold  conductance 

(

Au 25kHz,

 Column F in the data file) is a measure of surface contaminants.  

1.  The  low  frequency  gold  conductance  (

Au  10Hz,

  Column  G  in  the  data 

file) should not be used for analysis when operating with "No" coating. 

ii.  "Yes" should only be selected if a coating is applied to the gold IDE.  

For “Yes”, 

both the low and high frequency measurements can be used to quantify  coating 
barrier properties.
