Warning:  Doing  a temperature offset  adjustment  on a  channel  will  alter its  reading.  In  effect,  it alters  the 
thermometer own calibration. It must be used with care! 
 
To perform an offset adjustment, follow these instructions: 
 
1-  Click the “Offset Adjust” button ( ) that is just next to the channel number you want to calibrate. 
The following menu window is available: 
 
 
 
2-  Type in the “Set Point” box the actual temperature that you would like to force for this channel (this 
temperature is normally obtained using an accurate NIST-certified primary temperature reference). 
 
3-  Press the “OK” button to activate the reference temperature. The “Offset” value will reset to its new 
value,  as  a  result  of  your  new  forced  temperature;  this  new  offset  is  now  displayed  in  the  main 
window. 
 
4-  To reset this forced temperature setting, go back to the “Channel Offset” window, and click the Clear 
button. 
 
5-  Repeat the same procedure for the other channels that you want to modify. 
8.3  Acquiring and viewing temperature data 
Once all your thermometers are properly connected and configured, you may want to log data to a file, or to 
display their values on screen. A number of tools are available for that. 
 
To view or acquire data, the “Acquisition” pane must be active. 
8.3.1  Logging temperature data to a file 
FOB100-SOFT  offers  the  possibility  to log temperature  values to an  Excel compatible  file. The default file 
extension  is .tem; this file can be subsequently open  using Excel, which should  open  it  and automatically 
recognize as an Excel compatible file (tab delimited). 
 
The parameters that are useful to control the logging are shown in the lower left portion of the window, as 
shown here: 
 
 
 
•  To  set  the  logging  filename,  click  on  “SAVE  AS…”;  this  allows  you  to  enter  a  file  name.  For 
information, the current filename is displayed just below this button. 
 
•  To set the acquisition rate, enter a number, in seconds, in the appropriate text box. Rate can be set 
from 0.2 to 3600 seconds.
