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 CO
2
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 CO
2
scrubber when testing an instrument with a CO
2
sensor
installed to ensure that the CO
2
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 80 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
