For each instrument, this configuration window gives some information about this particular information and 
allows you to set some parameters. 
 
The top portion of the window gives information about the specifics of the thermometer, such as: 
•  COM Port number 
•  Serial Number 
•  Calibration date. 
 
Description of the parameters that can be set: 
 
•  Unit: You can select 
o
C or 
o
F. 
 
•  Scan Rate: Fast (recommended for most application) or Slow. 
 
•  Lock / Unlock Keypad (FOB100 series only): Can be selected to lock the keypad on the thermometer 
unit. Warning: once locked, the keypad can only be unlocked through the use of FOB100-SOFT or 
with the “l-“ serial command. 
 
Furthermore, for each channel, you can set the following parameters: 
 
•  On / Off: You can turn on or off the temperature for each channel. 
 
•  Name: Up to 16 characters. You can enter a probe name here that suits your application. 
 
•  Log: If checked, the temperature data for this channel will be logged, when data logging is active. 
 
•  Chart: If checked, the temperature data for this channel will be displayed when one of the 4 chart 
windows is open. 
 
•  Color: This is the color of the curve that will be used when the Chart window is open. 
 
•  Alarms,  Min  and  Max:  Allows  setting  alarm  limits.  When  one  of  more  alarms  are  detected,  a 
message  is  given  at  the  bottom  of  the  main  window  (must  be  in  Acquisition  mode).  For  a  given 
channel, alarms are monitored only when its corresponding “Chart” or “Log” checkbox is checked, in 
the Configuration window pane. Alarms are monitored only when Acquisition is active. 
 
•  Analog Outputs (FOB100 series only): Allows  configuring the analog output parameters, Zero and 
Span. See Section 6.3 for a complete description of these parameters. 
 
•  Offset: Allows adding an offset to this channel. See below. 
8.2.1.1  Adjusting a temperature offset 
FOB100-SOFT allows you to add an offset to the temperature readings that are returned by a thermometer. 
This feature is equivalent to the “f” serial command, as described in Section 6.3, although it implementation in 
FOB100-SOFT is somewhat different than it is for the serial command. 
 
An offset can be useful for the following two cases: 
 
1-  To temporarily change  the  reading of a  probe that is  believed  to be in  error (one-point calibration 
procedure). This usually requires that a good temperature reference be available. 
 
2-  To force  an  offset to  a  reading, for  example  may want to  monitor  a temperature  variation  from  a 
given  set  temperature.  In  this  case,  you  can  simply  enter  the  “0”  value  as  a  forced  temperature 
setting, and the resulting reading will give you a + or - deviation from the set temperature point.
