Loopback Test: (continued)
Modifying the Peakwin.ini File, (continued)
Find the PEAKWIN.lNI file in theWINDOWS sub-directory. Double-click to open it.
Scroll down until you find the [Lawson) section. Place the cursor at the last line of the
[Lawson] section and type "LoopbackFactor=X", and then press ENTER.
X is the value you calculated earlier. For example "LoopbackFactor=O.1003".

Press ALT-F then S to save the file. PressALT-F then X to exit. Restart
PeakSimple and load the loopback.con control file you saved earlier. Run the
loopback test again. The accuracy of the
D/A
converter shouid be improved. (Channel
1 toluene area counts should closelymatch the channel 4 toiuene area counts).
End of Test:
Turn off G.C. power and re-connect the original
AID
boardwiring. The loopback test is
completed.
