Breath Test
Criteria
Various criteria have to be met in order for
the 9
510 instrument to accept a breath
sample and ensure that the breath sample
analyzed represents an alveolar (deep lung)
air sample. The following conditions have to
be satisfied before the profile analysis is
activated:
Minimum flow rate 4.0L/min.
Minimum blow duration 5.0 sec.
Minimum breath volume1.5 L
Slope (plateau) detection
The plateau is reached if the concentration
increases ≤4%
in 1 second.
A successful breath test is characterized by
a nearly const
ant alcohol concentration in
time (plateau) at the end of the subject’s
sample.
Purging The internal pump flushes the cuvette and
breath hose with ambient air to ensure that
an alcohol and absorbing compound free
environment exists.
Ambient Air
Check
After the purging cycle, an air sample from
the cuvette is drawn into the EC sensor for
analysis. This procedure ensures that the air
in the cuvette is clear.
Air Blank
Check
After the ambient air check, the intensity of
the infrared energy is analyzed and stored
as a reference for successive IR
comparisons after purge.
Breath Test The subject’s breath is introduced through
the mouthpiece and the breath hose into the
cuvette. After the breath flow has stopped,
there is a short pause so that the pressure in
the cuvette reaches equilibrium with
ambient air pressure. Once equilibrium is
achieved, the intensity of the infrared energy
is analyzed. Immediately after the IR
analysis, the EC sensor pulls a 1 cc sample
out of the cuvette for analysis.
Mouth
Alcohol
Mouthalcohol is characterized by a sharp
i
ncrease of
the alcohol concentration at the
beginning of the subject’s breath sample
followed by a decrease until the end of the
sample (described in Section 9.1).
4 Description
4.1 Application
The Dräger Alcotest® 9510 is a breath alcohol analyzer used
for evidential breath alcohol measurements. The 9510
provides accurate, tamper-proof BrAC results which can be
displayed both on the instrument’s display and the printout
produced by the internal or external printer.
4.2 Product Description
The 9510 can be used in either a stationary or mobile location.
It comprises a graphic color display, multiple interfaces (USB,
Ethernet, Serial, and modem), and a comprehensive range of
adaptable accessories. The 9510 has an easy one-button
operation as well as a stylus stored in the recess on the top of
the instrument for touch screen operation. The 9510 features
a new ergonomic design and a low-noise thermal internal
printer with easy to read and durable document printouts.
4.3 Operating System
Two controller systems are active in the 9510; A Windows CE
operating system for the interfacing with peripherals, display,
external printer, communication via RJ-45 Ethernet, RS-232
Serial, etc. and the Renesas M16 controller system for the
handling of the measuring systems and for providing the
results directly to the internal printer.
4.4 Peripheral Connections
The 9510 has the following peripheral connections: (3) USB
ports, (2) RS-232 Serial Interfaces, RJ-45 Ethernet Interface,
External Video Monitor, AC/DC receptacles, RJ-11 Modem
Interface, Speaker, GSM, and an IR Port for wireless keyboard
or PC Communication.
4.5 Servicing
It is recommended that the 9510 instrument should have its
operation analytical accuracy verified every twelve months and
these checks should only be performed by Draeger Safety
Diagnostics, Inc., or a Dräger certified technician, or by trained
WSP personnel.
4.6 Cleaning
When cleaning the 9510 instrument, please follow these
guidelines (external only):
Disconnect power supply
Wipe outside of instrument with a damp cloth
Dry thoroughly
Do not use any solvents or cleaning agents
Do not allow liquids to enter the case or the Breath Hose
