1 • Overview
Chapter 1: Introduction
Overview
This chapter briefly describes the SDM-E2 Docking Station and the Single Module
Data Viewer Program. This chapter also describes the SDM-E2 Docking Station
Standalone Operation Operator’s Manual (this document). Table 1 at the end of this
chapter lists the SDM-E2’s specifications.
About the SDM-E2
The SDM-E2 Docking Station is an advanced, reliable system that provides charging,
calibration, bump testing, and calibration and bump test records for the EAGLE 2
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-E2 with the PC Controller
Program, see the SDM-E2 Docking Station PC Controller Configuration Operator’s
Manual.
The purpose of this manual is to explain how to set up and use the SDM-E2 in
Standalone configuration. It also explains how to use the Single Module Data Viewer
Program. You will learn how to:
• install and launch the Single Module Data Viewer
• prepare the SDM-E2 for use
• perform a bump test
• perform a calibration
• save calibration and bump test records to a USB flash drive
• view, print, and export calibration and bump test records
• use the SDM-E2 to charge an EAGLE 2

configuration. It is used for the PC Controlled configuration.
Instrument Panel
The instrument panel is located on the top of the SDM-E2 and includes the
instrument cradle, the exhaust bellow, the IR port, the charging cord, and a recess for
the fitting at the end of the gas out to EAGLE 2 line. The instrument cradle is a
recessed area on the top of the SDM-E2 that is designed to accept the EAGLE 2.
Insert the EAGLE 2 in the instrument cradle before you perform a bump test,
calibrate, or charge an EAGLE 2. The exhaust bellow is at the back of the instrument
panel and must line up with the exhaust port on the EAGLE 2 when it is in the cradle.
The instrument panel also has a protective metal loop to protect the exhaust bellow
and to prevent the EAGLE 2 from being accidentally dislodged from the cradle.
Follow the instructions in this manual and at the center of the instrument cradle for
installing the EAGLE 2 in the cradle to avoid damaging the exhaust bellow. An
infrared (IR) port at the rear of the panel lines up with the EAGLE 2’s IR port when it is
inserted in the cradle and is used to communicate with the EAGLE 2. The charging
cord and the fitting at the end of the gas out to EAGLE 2 line are stored in the

Chapter 3: Preparing to Use the SDM-E2
Overview
There are four tasks that must be completed before you can begin to use the
SDM-E2: 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-E2 and set or view the bump test and calibration
parameters. It also describes 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-E2 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-E2.
NOTE: If you have multiple SDM-E2s 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-E2s.
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-E2.
NOTE: If you have an EAGLE 2 with an IR CO2 sensor in the 0-10,000 ppm or
0-5.00 %vol range, be sure to replace the air filter at the AIR inlet fitting
with the CO2 scrubber when testing an instrument with a CO2 sensor
installed to ensure that the CO2 present in fresh air is scrubbed out.
Remove the black end caps from each end of the scrubber before
installing onto the AIR inlet fitting. Replace the caps when the scrubber
is not in use. See the “Spare Parts List” on page 81 for a scrubber with
a tubing stub.
5. Install the 10 foot long 3/16 inch ID flexible tube that is included with the SDM-
E2 on the exhaust fitting. Route the tube to an area where the exhaust can be

13 • Setting the Operational Parameters in Edit Mode
safely dispersed, such as an open window.
CAUTION: The maximum recommended length for the exhaust tube is 30 feet. Do
not use more than 30 feet of tubing or tubing with an ID of less than
3/16 inch for the exhaust tube or the bump test and calibration
accuracy may be adversely affected. The tube that is shipped with the
SDM-E2 has an ID of 3/16 inch and is 10 feet long.
6. Install the 3 foot long 3/16 inch ID tubes that are included with the SDM-E2 on
the GAS 1 and GAS 2 fittings.
Setting the Operational Parameters
in Edit Mode
Once the hardware has been assembled, use Edit Mode to confirm or adjust bump
test, calibration, and gas inlet parameters before using the SDM-E2.
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 gas inlet parameters define what gas inlet fittings (GAS 1, GAS 2, or both) will be
used during bump tests and calibrations.
The bump test and calibration parameters are saved in the SDM-E2’s memory. If a
parameter is changed with one particular EAGLE 2 installed in the SDM-E2, the
change will be in effect for the bump test or calibration of any subsequent EAGLE 2
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

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 TIME)
The air sample time can be set separately for bump testing and calibration. It is the
length of time that the SDM-E2 will draw air through the AIR fitting on the back of the
docking station. Air is drawn during a bump test or calibration before an air adjust
operation and to purge calibration gas from the system after calibration gas has been
drawn through the GAS 1 or GAS 2 fittings on the back of the docking station.
Calibration Gas Sample Time (GAS TIME)
The calibration gas sample time can be set separately for bump testing and
calibration. It is the length of time that the SDM-E2 will draw calibration gas through
the GAS 1 or GAS 2 fittings on the back of the docking station during a bump test. If
the GAS TIME is set to AUTO, the SDM-E2 applies calibration gas for the appropriate
amount of time based on the sensors installed in the EAGLE 2.
Bump Test Check Tolerance (CHECK)
The bump test check tolerance only applies to bump testing. It determines how close
the EAGLE 2 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 EAGLE 2 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 EAGLE 2 must be 50 %LEL ± 25 %LEL.

The F±10%, F±20%, F±30%, 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
TIME 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 sensor respond quickly and accurately.
Consider the following scenario as an example.
• 50% LEL methane used for bump testing the combustible gas channel
• GAS TIME bump test parameter set to 20 seconds
• Tolerance set to F±50%, 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 (AUTO 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-E2 with an EAGLE 2
Do the following to turn on the SDM-E2 and establish a connection with an EAGLE 2:
1. Confirm that the AC Adapter is connected to the SDM-E2 and to an AC wall
socket.
2. Press and hold the SDM-E2’s POWER button. The LEDs will turn amber.
3. When the BUMP  and CAL  LEDs turn off, release the POWER button.
