Understanding the log file

If the Log Console Messages check box is selected (lower left of the user interface), KXCI logs all
GPIB commands to a file named KXCILogfile.txt. You can open the text file after KXCI is closed.
Note that whenever you open KXCI, the log file clears.
The log file is in the directory:
C:\s4200\sys\KXCI\
You can use any text editor to open the file.
Note that SMUs may return a line such as:
DATA:NAI 22.329E-09
The three characters after DATA: represent:
•
The operating condition: N for normal or C if the SMU is in compliance.
•
The instrument number, converted to a letter: A for SMU1, B for SMU2 and so on to letter I.
•
The measurement function: V for voltage or I for current.
