About the SDM-2009
The SDM-2009 Docking Station is an advanced, reliable system that provides
charging, calibration, bump testing, and calibration and bump test records for the
GX-2009 portable gas monitor. 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-2009 with the PC Controller
Program, see the SDM-2009 Docking Station PC Controlled Configuration Operator’s
Manual.

Chapter 3: Preparing to Use the SDM-2009
Overview
There are four tasks that must be completed before you can begin to use the
SDM-2009: 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-2009, 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-2009 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-2009.
NOTE: If you have multiple SDM-2009s and are using a 4-port AC adapter,
plug each of the round plugs on the end of the AC adapter into the
power jack on the back of 4 separate SDM-2009s.
4. 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-2009.
5. Install the 10 foot long 5/16 inch ID flexible tube that is included with the SDM-
2009 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
SDM-2009 has an ID of 5/16 inch and is 10 feet long.
6. Install the 3 foot long 3/16 inch ID tube that is included with the SDM-2009 on
the GAS fitting.

14 • Setting the Operational Parameters in Edit Mode
Setting the Operational Parameters
in Edit Mode
Once the hardware has been assembled, use Edit Mode to confirm or adjust the
bump test and calibration parameters before using the SDM-2009.
The bump test parameters define how long fresh air and calibration gas are applied to
an instrument during a bump test. They also define the tolerance used in determining
whether an instrument fails or passes a bump test and whether or not a calibration
automatically takes place if a bump test fails. The calibration parameters define how
long fresh air and calibration gas are applied to an instrument during a calibration.
The bump test and calibration parameters are saved in the SDM-2009’s memory. If a
parameter is changed with one particular instrument installed in the SDM-2009, the
change will be in effect for the bump test or calibration of any subsequent instruments
until the parameter is changed again.
Bump Test & Calibration Parameters
There are four bump test parameters and two calibration parameters. The two
calibration parameters, air sample time and calibration gas sample time, are also
bump test parameters. The parameters are described below. Table 3 below shows
the factory settings for the bump test and calibration parameters. If you wish to use
the factory settings, then you do not need to make any parameter adjustments. If you
wish to confirm or change the parameter settings, follow the instructions below in
“Setting the Bump Test Parameters” on page 18 or “Setting the Calibration
Parameters” on page 20.

Air Sample Time (AIr)
The air sample time can be set separately for bump testing and calibration. It is the
length of time that the SDM-2009 will draw air through the AIR fitting on the back of
the docking station before an air adjust operation.
Calibration Gas Sample Time (GAS)
The calibration gas sample time can be set separately for bump testing and
calibration. It is the length of time that the SDM-2009 will draw calibration gas through
the GAS fitting on the back of the docking station during a bump test or calibration.
Bump Test Check Tolerance (CHE)
The bump test check tolerance only applies to bump testing. It determines how close
the instrument gas reading must be to the calibration gas concentration for each
channel during a bump test in order to pass the bump test. It is defined as a
percentage of the calibration gas concentration. The amount that the instrument gas
reading differs from the calibration gas concentration must be equal to or less than
this percentage of the calibration gas concentration. For example, if the tolerance is
set to 50%, and the %LEL calibration gas concentration is 50% LEL, then the bump
test gas reading for the LEL channel on the instrument must be 50 %LEL ± 25 %LEL.
The F10, F20, F30, etc. options represent a fast bump tolerance. If one of these “F”
type tolerances is selected and the gas reading for the sensor(s) being tested is
above the lower tolerance and below the upper tolerance within 10 seconds, the
sensor(s) pass bump testing, the gas application will be stopped, and the test will
move on to the next sensor(s) or to the fresh air purge. If the gas reading on any of
the tested channels is below the lower tolerance or above the upper tolerance within
10 seconds, the gas application will continue for the time period defined by the GAS
bump test parameter, and the pass/fail status of the sensor(s) will be determined at
that point. Using an “F” type tolerance allows calibration gas to be saved when the
tested sensors respond quickly and accurately.

16 • Setting the Operational Parameters in Edit Mode
Consider the following scenario as an example.
• 50% LEL methane used for bump testing the combustible gas channel
• GAS bump test parameter set to 20 seconds
• Tolerance set to ± F50%, which means that the acceptable reading range is 25%
LEL - 75% LEL
The table below shows possible readings at 10 seconds and the effect on the gas
application.
Automatic Calibration (CAL)
Automatic calibration only applies to bump testing. It can be set to on or off. If it is set
to on, then the docking station will automatically perform a calibration if a bump test
fails.
Turning on the SDM-2009 with an Instrument
Do the following to turn on the SDM-2009 and establish a connection with an
instrument:
1. Confirm that the AC adapter is connected to the SDM-2009 and to an AC wall
socket.
2. Press and hold the SDM-2009’s POWER button. The LEDs will turn amber.
3. When the BUMP  and CAL  LEDs turn off, release the POWER button.
4. The COPY LED will be steadily on or off and the CHARGE LED will be blinking
green if the SDM-2009 is operating properly or solid red if there is a system
failure. The amount of free memory in the SDM-2009 will dictate the condition
of the COPY LED (see “Available Memory in the SDM-2009” on page 39).
5. Install an instrument into the instrument cradle.
6. Press and hold the POWER MODE button on the instrument until you hear a
beep, then release it. The instrument will begin its power up sequence (see
