Chapter 4: Operation
Overview
When you have completed the tasks in "Chapter 3: Preparing to Use the SDM-E2",
you are ready to use the SDM-E2 docking station. The SDM-E2 is capable of
performing bump tests and calibrations on the EAGLE 2. It can also charge the
optional rechargeable NiMH batteries in the EAGLE 2. This chapter describes
procedures for using the docking station to bump test, calibrate, and recharge
EAGLE 2s in the standalone configuration of the docking station. It also describes the
information that is saved in the docking station’s memory and how to save that
information to a USB flash drive for use with the Single Module Data Viewer Program.
Bump Testing Instruments with Standard
Sensors
The following instructions apply to EAGLE 2s with one or more of the standard four
sensors (catalytic LEL, O
2
, CO, and H
2
S). If your EAGLE 2 includes one or more
special sensors such as a TC, PID, ESM-01, etc., see “Bump Testing an Instrument
with Special Sensors” on page 41 for bump testing instructions.
When a bump test is performed, the SDM-E2 performs a fresh air adjustment on an
EAGLE 2 and then applies calibration gas to the instrument. The docking station then
analyzes the response results based on criteria defined by the bump test check
tolerance parameter and determines if the instrument passed the bump test. The
bump test check tolerance is defined in “Bump Test Check Tolerance (CHECK)” on
page 14. If the automatic calibration parameter is set to ON, then the SDM-E2 will
automatically perform a calibration if the bump test fails.
Do the following to perform a bump test:
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
T
and CAL
S
LEDs turn off, release the POWER button.
4. The COPY LED will be off or on steadily and the CHARGE LED will be blinking
green if the SDM-E2 is operating properly or solid red if there is a system
failure. The amount of free memory in the SDM-E2 will dictate the condition of
the COPY LED (see “Available Memory in the SDM-E2” on page 68).
