About the SDM-2012
The SDM-2012 Docking Station is an advanced, reliable system that provides
charging, calibration, bump testing, and calibration and bump test records for both the
GX-2012 and Gas Tracer portable gas monitors. It is designed to save the calibration
and bump test records to a USB flash drive (standalone functionality) or to be
connected directly to a computer (PC controlled functionality). If calibration and bump
test records are stored to a USB flash drive while operating in the standalone
configuration, the Single Module Data Viewer Program can then be used with a
Windows-based personal computer to retrieve calibration and bump test data files
from the USB flash drive or from the computer’s hard drive if the files have been
transferred to the hard drive from the flash drive. If you are using the PC Controller
Program while operating in the PC controlled configuration, you may retrieve
instrument data, bump test, and calibrate up to 10 instruments at once. Instrument
information and data for each instrument can be viewed directly using the PC
Controller Program and can be printed from the PC Controller Program. For
instructions to use the SDM-2012 with the PC Controller Program, see the SDM-2012
Docking Station PC Controlled Configuration Operator’s Manual.
The purpose of this manual is to explain how to set up and use the SDM-2012 in
Standalone configuration. It also explains how to use the Single Module Data Viewer
Program. You will learn how to:

Chapter 3: Preparing to Use the SDM-2012
Overview
There are four tasks that must be completed before you can begin to use the
SDM-2012: hardware assembly, setting or confirming the bump test and calibration
parameters, connecting calibration gas, and installing the Single Module Data Viewer
Software on your computer. This chapter describes how to assemble the parts that
are shipped with the SDM-2012, how to set or view the bump test and calibration
parameters, and how to install the Single Module Data Viewer Software on a
Windows based personal computer.
Hardware Assembly
The hardware assembly consists of connecting the AC adapter, installing the air filter,
and connecting the sample tubing. Perform the following to complete the hardware
assembly:
1. Place the SDM-2012 on a convenient table top near an AC wall socket in a
well ventilated area. A location near a window that can be opened is best so
that the exhaust can be routed to the window.
2. Connect the AC adapter’s wall plug into a wall AC socket.
3. Insert the round plug on the end of the AC adapter’s cable into the power jack
on the back of the SDM-2012.
NOTE: If you have multiple SDM-2012s and are using a 3-port AC adapter,
plug each of the round plugs on the end of the AC adapter into the
power jack on the back of 3 separate SDM-2012s.
4. Install the exhaust line, a clear 12 inch long tube with a black plastic push-on
fitting, by pushing the open end of the exhaust tube onto the exhaust line
connection fitting located in the upper left corner of the instrument panel. You
may then push the black push on fitting of the exhaust line onto the exhaust
line storage fitting on the other side of the instrument panel.

15 • Hardware Assembly
5. Install the air filter so that the arrow on the filter that indicates direction of flow
is pointing towards the AIR fitting. Push the open end of the flexible tube that is
on one end of the filter onto the AIR fitting on the back of the SDM-2012.
6. Install the 10 foot long 5/16 inch ID flexible tube that is included with the SDM-
2012 onto the exhaust fitting located in the upper left corner of the back panel.
Route the tube to an area where the exhaust can be safely dispersed, such as
an open window.
CAUTION: The maximum recommended length for the exhaust tube is 10 feet. Do
not use more than 10 feet of tubing or tubing with an ID of less than
5/16 inch for the exhaust tube or the bump test and calibration
accuracy may be adversely affected. The tube that is shipped with the
