When ready to collect data press the “Start/Stop” 
button on the salinity sensor, a red light will turn 
on for the duration of the experiment. 

3.

 

To change the experiment settings first connect to 
your  chosen  device  (PC,  Mac,  tablet,  smart 
device)  and  select  the  “Module  setup”  button.  
(For  more  information  on  how  to  change  the 
experiment  settings  view  quick  start  procedure 
section for your chosen device in this document.) 

4.

 

After  the  experiment  has  concluded  (when  the 
“Start/Stop”  button  is  pressed  again  or  the  data 
collection period ends) connect the sensor to your 
chosen device. (full instructions in each device’s 
quick start procedure section) 

5.

 

Open Edu-Logger software. 

6.

 

Click the “Off-line experiment” button. 

7.

 

Click the “Load data from sensors” button.  

8.

 

Select  which  experimental  data  to  upload.  (5 
experimental  runs  can  be  stored  at  one  time  on 
the 900-238 salinity sensor)

Procedure: 

1.

 

Connect  the  900-213  to  a  PC,  Mac,  tablet,  or 
smart device. 

2.

 

Connect the  salinity sensor to a  900-213 module 
(they directly plug together).  Please note there is 
no calibration required for this sensor. 

3.

 

Open the Edu-Logger software. 

4.

 

Click the “Tools” icon. 

5.

 

Click  the  “Restore  sensor’s  factory  defaults”  on 
the menu. 

6.

 

If  prompted  to  clear  the  graph,  click  either  the 
“Off-line  experiment”  or  “On-line  experiment” 
(whichever you are using). 

7.

 

Click “Clear experiment results”. 

8.

 

Resume from step 4.
