Remote Calibration Mechanical Installation (Optional)
You can use the Series 2000 control unit to automatically switch between
calibration and sample gases. To do this, you can use either the optional
factory-provided remote calibration unit (see the “Factory-Provided Re-
mote Calibration Unit Setup” section below), or the signals from the con-
trol unit to create your own remote calibration sequence using your own
control valves to switch between the process and calibration gases (see the
“Customer-Supplied Remote Calibration Initiation” section that follows).
