RKI Instruments GX-2001 Data Logging with Calibration Station - Manual (Page 21)

Overview of the GX-2001 Calibration Station • 21
There is an LED on the top left of the Charger/Downloading
Station, which turns on after the Model GX-2001 has been
placed in the Data Logging/Charger Station and the power cord
for the Data Logging/Charger Station has been plugged into an
electrical outlet. When the Model GX-2001 has been fully
charged, this light goes off.
The Calibration Adapter is attached to the right side of the
Charger/Downloading Station. It routes sample gas over the
sensors of the Model GX-2001. On the right side of the
Calibration Adapter are two hose barbs, Cal In and Cal Out. The
Cal In hose barb is toward the back of the Calibration Adapter
and has a tube connected to it which routs span gas and fresh
air to the Calibration Adapter from inside the calibration station.
The Cal Out hose barb is toward the front of the Calibration
Adapter and is not connected to any tubing. It may be used to
connect up to 10 feet of 3/16” I.D. tubing to route the exhaust to
a hood or outdoors.
CAUTION: Do not connect more than 10 feet of tubing to the
Cal Out fitting. Connecting more than 10 feet of
tubing to the Cal Out fitting will result in an
inaccurate calibration of the GX-2001.
To the right of Cal In and Cal Out hose barbs is a black button
which, when pushed in, secures the Model GX-2001 to the Data
Logging/Charger Station. Next to the black button is a metal
release lever which, when pressed down, releases the Model
GX-2001.
On the back of the Data Logging/Charger Station is a data
connection (made at the factory) which is used to transfer data
from the Model GX-2001 to the GX-2001 Calibration Station,
where it is then transferred to the computer.
