The screen saver option lets you blank the display screen when it is not being used. SW1-8 OFF
activates the screen saver, while SW1-8 ON disables this feature.
If the GCC has user nameable inputs option, you may insert names for up to five sensor inputs

You can verify a chromatogram's zero baseline in one of the following ways:
•
Record the chromatogram, to compare it with the Data Package
•
Display the chromatogram
•
Display the percent offset used to achieve zero
