General Information
Congratulationsonyour purchaseofan EMSExhaustGasAnalyzer.Thisproductisde-
signedtoassist you in theprocess of diagnosing driveabilityissues.With proper careandmain-
tenancethis productwill provideaccurateinformationformanyyearstocome.
IMPORTANTNOTE: Moisture is the biggest concern for prolonged good operation of the gas
analyzer. Always allow the analyzer to dry out by running the unit with ambient air. This may take only
one auto shut down cycle or as much as a couple hours! The analyzer will not be harmed by powering up
and letting it sit in standby mode till ready to use. Running the analyzer with ambient air in-between
sampling and after a day of testing, is the best thing to do for prolonged life of the bench and compo-
nents not allowing carbon build up due to moisture!
Figure 1 highlights the features and buttons available on the Model 5003 front display
area. The HC will display up to five digits and is in ppm, CO is in percentage, CO2 is in percent-
age, NOX is in ppm, O2 is in percentage, LAMBDAand AFR. The buttons will be described
laterinthis manual.

Rear Panel Description
Figure3shows theview fromtheback ofthe analyzer.The specificdetailsofeach
itemare describedbelow,starting fromthe upperleftcorneroftheanalyzer andworking
clockwise.
Sample Hose Connection: The sample hose connection uses a quick disconnect
coupler.This ishelpfulforstorageoftheanalyzerandmaintenanceofthesamplehose.
Theinlet isconnectedtoaOil/Waterseparatorforpre-moisture extraction.
Display Control Switch: The display switch has two basic positions, Computer and
Display. The switch should normally be in the DOWN position “Display”. If you are using
PC software for display or recording, the switch should be in the UP position. Note: The
switch direction is based upon you looking at the display. The switch should be
changed only with power turned off.
DB9 Computer Connection: This is used to connect the analyzer to your PC/laptop or
wirelessantenna.
Power Cord: Connect to the appropriate voltage supply source.
Sample Air Exhaust: The analyzer discharges the sample air out these ports. Do not
plug..
Drain Hose: This hose will drain moisture collected during the sample process.
External Filter, Water Trap, Water/Oil Separator: This is the primary filtration system.
Filter maintenance will be discussed in the Maintenance section of this manual.
Water Separator Drain: Drain daily opening a ball valve.

Gas Analyzer Preparation
Getting started is simple. Figure 4 shows the items you should have received in the
shipping container. Note: This description applies to the Model 5003 analyzer with a live
reading only display. The first step is assembling the sample hose. Once the sample hose,
handle and S.S. probe are assembled, connect the hose to the sample hose QD fitting on the
inlet connection of the water/oil separator.
Figure 4
The next step is providing power to the analyzer. The analyzer should be connected to a
12v DC power source. You have several options:
1. Cigarette Lighter Connection - Figure 5 (Supplied by EMS)
2. Cigarette lighter to battery connection with adapter - Figure 6 (Optional)
3.AC to DC Power Supply - Figure 7 ( 5AMP min. and 10AMP) (Optional)
Figure 5 Figure 6 Figure 7
NOTE: Power supply voltage to the analyzer needs to be a consistent 12 VDC. If any
start up issues occur check power supply or battery.

Gas Analyzer Operation
Shortlyafterapplyingpower, theanalyzer willdisplay theEMS logo& worldstartupscreen.
Itwilldisappear onceand reappear(Figure8) forapprox.15 sec.thenswitch totheHome sampling
screen(Figure 9).This startsthe analyzerwarm-up modeand willcontinue forapproximately 5to
10minutes, dependingon ambienttemperature. Oncethe warm-upiscomplete,theanalyzerwill
gointothe“ZEROING”mode toset allthegases tozero. Thenthegas samplemode will displayall
the gas values (Figure 10). 4 Gas units will show CO2, CO, HC, O2 (figure 11) Note: Below the
gas data is a status line where operations and/or errors will be displayed.
Figure 8 Figure 9
Figure 10
Once the analyzer has completed the warm-up, the sample hose can now be connected
and the probe placed in the tailpipe.
Caution: Exhaust gases pass through the gas analyzer and vent through its ex-
haust. Use the analyzer in a well vented area. EMS can supply a venting hose assembly.
Note: Gas analyzers are designed for diagnostics and verification of repairs. The
sample probe should be removed from the tailpipe after taking readings to prolong
analyzer life and save on maintenance costs.
Caution: Monitor the clear hose between the filter assembly and the housing. If
moisture appears in the tubing, remove the probe from the tailpipe and disconnect the
sample hose from the analyzer immediately. Use compressed air to remove moisture from
the sample hose. Operate the analzyer without the exhaust sample hose connected until
the moisture is removed. It may be necessary to replace the filters. Once the lines are dry,
normal operation can continue.

Gas Analyzer Operation
Manual Zero:Anytime afterwarm-up, youcanzero thegas readingsandcalibrate O2by
pressingthe “ZERO” button(Figure12).Oncethe buttonis depressed,you willsee thebutton
turnredshowingthebutton wasdepressed (Figure13).When thisoperation isbeingdone “ZE-
ROING”will bedisplayed inthestatusline(Figure14) andwill flushthe benchfor 30sec. with
ambientair frominsidetheanalyzer. Ifthe pumpsare shutdown, pushthe“ZERO”buttonand the
pumps willautomaticallystart. Note: The sample probe should be removed from the tailpipe,
when the unit is being zeroed.
Request Zero: The analyzerwill automaticallyrequest azero asneeded. Ifthe analyzer
requestsa zeroduring sampling,you canfinish yourtest firstbefore Zeroing.Thebenchcontrols
theZero requests,normallyafterseveralhours ofrunningthebenchwill notrequestaZero,but
longsampling ordrift maycause thisrequest. Ifany readingsare jumpydue tocontamination, just
keepthe pumpsrunning andZerooftentillthereadingsstabilize.
Figure 15
Low Flow Warning: If gas flow into the bench becomes restricted due to clogged filters or re-
strictedsamplehose, thestatus line will indicate “LOW FLOW” (Figure15) andthe pumps
wouldshutoff. To cleartheLOW Flowwarning, gotothe Leakcheck screentoperform aleak
test.Disconnect andcheckthe samplehose forrestrictions orkinks.If noproblems arefound,
checkthe filters.Begin withthe Externaland watertrap filter thencheck theInternal filter.Keepin
mind,the watertrapassemblythegasflowsthrough theinside tothe outsideofthe filter.The filter
maylookclean ontheoutside, butbe clogged onthe inside. Thebest check isto lookatthe
bottomof thewatertrap filter.If the LOW FLOW continuesto bedisplayed, thesolenoid valvewill
needtobe checkedor possibly replaceddue tocarbonbuildup. Pumpswillstart oncethe restric-
tion is cleared.

The gas analyzer should be checked periodically for accuracy. For normal shops using
the analyzerthis wouldbe approx.3-6 months,for higherusage approx.every 1monthormore.
Theanalyzer canbe calibratedinthefield.Inordertoperformthe calibrationprocedure youwill
need a bottle of calibration gas and a calibration kit (Figure 17). The calibration Kit (EMS-5500)
canbepurchased fromEMSor your localdistributor.The recommendedcalibrationgas is Bar97
Low and can be purchased from EMS, Part No.EMS-5502; BAR 97 LOW.

Calibration

NOTE: Thehydrocarbongas inthe calibrationcylinderis propane(LPG), andthegas
analyzer generally measures hexane. This is problematical, as hexane is a molecule that
is about twice as large as propane. This means that the typical HC reading on the gas
analyzer(hexane) shouldbe about½ thepropane value(Figure25)onthecalibration
cylindertag. Thatis,ifthetag statesthat thecylinder contains1200 ppmpropane, thenan
analyzermeasuringHC ashexane willreportHC atabout 600ppm.The PEFvalue (
Propaneequivalence factor)can beused tocalculate theHexane gasvalue. Youhave
accessto thebenchPEF valuein theSETUPMenuscreen.Youcanalso gointo thefuel
selectionscreenand pickLPG foran accuratecalibrationgas valuethat thedisplaycalcu-
lates automatically. NOTE: EMS recommends allowing the analyzer to warm up for a
min. of 1 hour before calibrating. You may also need to calibrate more than once to
get the Nox sensor to calibrate more accurate, ecspeacially for BAR 97 HIGH gas.
If checking accuracy you will also see the Nox get more accurate as you allow the
analyzer to run, warming up all the sensors to a consistent temperature approx. 2-
3 hours.
After calibration you will see a Bad Nox sensor message, this is a False error we
can’t seem to eliminate! Zero the analyzer on the Home screen to clear the error
message.

probe with the red/black plastic cap supplied by EMS. The same low flow codes will come up
as described above and the low flow should hold for the duration of the test. If a leak is de-
tected, meaning the pumps turn back on losing vacuum, the most common leak is at the external
filterbowl connection. Thiscanbeverifiedbyusingabutanelighter openingraw butanenext to
