GC-2014
When connecting the GC to a C-R7A/CR-7A plus for the first time, or replacing
the Chromatopac, set the detector signal output to “Off” and perform
calibration. (For the calibration procedure, refer to “2.2 Outputting Analog
Signals to the Chromatopac”.)
Linear...Select linear when connecting the GC to any Chromatopac other than the C-
