GC1000 Mark II analyzer (hereinafter referred to as the “analyzer”) on a personal computer by
linking the computer to the analyzer through a communication line. The figure below illustrates an

n Features of the Maintenance Terminal
The Maintenance Terminal features:
l Remote Operation of LCD Panel
The LCD screen of the analyzer is duplicated onto the CRT screen of your personal computer.
Thus, you can manipulate the LCD screen from a location distant from the field.
l Analyzer Operation Window Presenting an Overall View
The current operation mode, valve and detector statuses, and a chromatogram are displayed in
one window (Analyzer Operation window). This gives a convenient view of the operating status at
a glance. Just click on an object in the window to change the mode, open and close valves, view
the detailed chromatogram, etc.
l Uploading and Downloading Analyzer Parameter Settings
Parameter settings can be uploaded and downloaded, thus allowing the parameters set on the
LCD panel to be also set in another analyzer.
l Detailed Chromatogram Display and Data Saving
A chromatogram is displayed in two ways: the Analyzer Operation window which shows
an overview of the chromatogram and the Chromatogram window which provides a more
detailed view of it. The Chromatogram window allows zooming, changing scales, and saving of
chromatogram data.
