I have a 6850 GC with FID detector. The GC reports a signal of +5.8 pA.
The OpenLab Instrument actuals window reports the signal correctly at +5.8 pA.... but the Online Signal window reports (draws a baseline) of -1.8 pA!
I have rebooted everything and nothing explains why OpenLab can for no reason that I have been able to conclude, display a negative value on the Online Signal view window.

Anyone?
