INTOXILYZER®S-D2 Operator’s Manual

INTRODUCTION
The Intoxilyzer®S-D2
representsa wellestablished
conceptinbreathalcohol
testing analysis. It is used
worldwideinlawenforce-
ment,transportationand
workplace safety applications. The S-D2 is just
oneof the range of instruments manufactured by
CMI, Inc. for these purposes.
TheIntoxilyzer®S-D2isaccurate and reliable,
allowinga complete breath test procedureto be
conducted in about one minute.
Thismanualdescribes the operation,
maintenance,calibrationcheck,and calibration
adjustment of the S-D2. This manual should be
readcompletelyandfullyunderstoodbyeach
operator prior to testing a subject. It is further
recommendedthatoperatorspractice the breath
testing process before giving an actual “in the
field” test.
The information contained in this manual concerning operational
procedures, protocols, accuracy verification schedules and
techniques is presented solely for the purpose of establishing a
general knowledge of the instrument and its operation. CMI
recognizes that many law enforcement customers have
agencies responsible for specifying instrument procedures,
protocols and techniques based upon their individual needs,
current laws and pre-existing administrative rules. Therefore, if
any such procedure, protocol, schedule or technique described
in this manual conflicts with the rules set forth by a recognized
governing agency, CMI defers to those authorized entities.

PRINCIPLES OF
OPERATION
TheIntoxilyzer®S-D2
usesan electrochemical
fuel cell, containing two
platinumelectrodes,to
detectandmeasurethe
concentrationof alcohol vapor in expired breath.
When breath is drawn into this fuel cell, by means
of the sampling system, a small voltage is
generatedinproportiontoitsbreath alcohol
concentration. This fuel cell is fed to an electronic
amplifier and displayed on a digital meter (liquid
crystal).
The S-D2 incorporates two breath sampling lights,
controlledbyaninterlinked pressure switch and
timer system. The sampling lights show the
operator if the subject is blowing correctly, and
whenhehasprovided a suitable sample of breath
foranalysis.
The instrument is simple to operate and may be
usedasoftenasrequired,providedthatasuitable
delayis allowed between successive tests. This
time delay allows the fuel cell to clear itself of
alcoholandpreventsthepossibilityofadditive
readings. If no alcohol is present in a test, a
secondtestmay be analyzed immediately, since
the fuel cell voltage is already at zero. Unless the
breath alcohol level of the subject is very high,

theinstrument will generally beclear enough toreceive
and analyze the second sample in less than two minutes.
INSTRUMENT FEATURES
1)Mouthpiece
This is attached to the sampling port. For
hygenicreasons, mouthpieces are supplied
separatelypackedandaredisposable. Anew
mouthpiece must be used for each breath test.
Thisminimizeshealth concerns and prevents
cross-samplealcohol contamination.
2) Sampling Port
This forms the entrance to the fuel cell detector.
When inserted into the small hole in the side of
the mouthpiece, it allows a small portion of
breath to be drawn into the instrument for
analysis.
3) ‘SET’ Button
This button forms part of the sampling system.
When fully depressed, the button locks to set
the instrument ready for sampling. When the
‘SET’ button rises, the sample to be analyzed
is drawn directly into the fuel cell detector.
4) ‘READ’ Button
This button has two functions:
1) to release the ‘SET’ button and take
thesample,
2) to switch on the amplifier and display
systems

5)AlcoholLevelDisplay
This three digit, liquid crystal display shows
thebreathalcoholconcentrationof the subject.
The display has built-in illumination and is
activatedbydepressing the ‘READ’ button.

6)Calibration Control
This screw control, located on the right side of the
case,isusedforperiodic calibration adjustments
with either a dry gas standard or wet bath
simulator.
7) Breath Sampling Lights
Light ‘A’ illuminates to indicate that the subject
is blowing hard enough to obtain a proper breath
sample. Light ‘B’ illuminates when the subject
has blown long enough and indicates when the
‘READ’ button should be pressed. In other
words, light ‘B’ illuminates when the subject has
providedasuitable sample for breath analysis.
8)Battery
The battery is located directly behind the sliding
base on the bottom of the S-D2. It powers the
amplifier, digital display and sampling lights and

should be replaced when the letter ‘L’appears on
the left side of the display.
9)Leather Case
The S-D2 is supplied in a leather protective case.
The unit should be kept inside the case at all
times, except when calibrating, changing the
