the Model GX-2001 with the Calibration Station • 45
Preparing for Calibration
1. Plug the power cable of the GX-2001 Calibration Station into
a 115 VAC electrical outlet.
2. Plug the power cable of the Data Logging/Charger Station
into a 115 VAC electrical outlet.
3. Connect one end of the data cable to the computer
connector on the back of the GX-2001 Calibration Station.
Connect the other end of this cable to the computer’s serial
port. Refer to your computer’s documentation for the location
of the serial port.
4. Check the data cable connection between the Charger/
Downloading Station and the charger connector on the back
of the GX-2001 Calibration Station. This connection was
made at the factory.
5. Connect up to 10 feet of 3/16” I.D. flexible tubing to the Cal
Out hose barb on the Calibration Adapter on the top of the
Calibration Station. Make sure to run this tubing to an
exhaust hood or outdoors away from fresh air vents and air
conditioning ducts. Alternately, you may place the GX-2001
Calibration Station underneath an exhaust hood.
(Remember to turn on the exhaust hood before calibration
begins.)
CAUTION: Do not connect more than 10 feet of tubing to the
exhaust fitting. Connecting more than 10 feet of
tubing to the exhaust fitting will result in an
inaccurate calibration of the GX-2001.
6. If necessary, connect flexible tubing to the Fresh Air In fitting
on the back of the GX-2001 Calibration Station. Use this
fitting if you suspect that the area around the GX-2001
Calibration Station is not a fresh-air environment and you
want to draw fresh air from a remote location.
7. Screw the regulator onto the calibration gas cylinder.
