AUTOplus manual
Page 8
3. FIRST TIME USE
Charge the battery for 12 hours; following this an overnight charge should be
sufficient for an average 8-hour day (turning pump off to save power between
tests).
The analyzer has a rechargeable NiMh battery, use only the mains charger or
12 volt adapter supplied or damage may occur to the analyzer and battery.
Check that you have all the items you have ordered.
Take time to read this manual fully.
When using the analyzer for the first time you will need to choose from: -
Language selection
Time and date
Printed header name and telephone number
4. NORMAL START UP SEQUENCE
4.1 Every Time You Use The Analyzer
BEFORE SWITCH-ON CHECK THAT:
The particle filter is dry and not dirty or damaged
The water trap and probe line are empty of water
All hose connections, etc, are properly made
The probe is sampling CLEAN AMBIENT air
The water trap is correctly fitted and the analyzer upright
* DO NOT RUN ANALYSER WITHOUT WATER TRAP FITTED *
Switch ON the analyzer by pressing

4.2 Automatic Zero Calibration
During this sequence the analyzer pumps fresh air into the sensors to allow
them to zero and the oxygen sensor to be set to 20.9 %.
After switch-on the analyzer will briefly display information:

The time will count down in seconds to zero and is pre-set by the analyzer.
During countdown the analyzer will initialize the measuring system, do not block
the end of the probe or insert into or near the vehicle exhaust. It also displays
some setup values including atmospheric pressure and internal ambient
temperature.
TIP: Take care to purge the analyzer in really fresh air. Often the air in a
garage or workshop is contaminated with HC up to about 1 meter from
the floor with the emissions from past spills of oil, lubricants etc that may
have soaked into the floor.
Once the initialization is completed the analyzer will zero the CO, HC, CO2 and
NO sensors if fitted and set oxygen to 20.9%. Keep the analyzer and exhaust
probe sampling fresh air.

4.5 Sampling the Exhaust Gas
Once the zero calibration and test procedures have been completed and the
fuel has been selected the probe can be inserted into the desired vehicle
exhaust.
Ensure the probe is inserted into the exhaust pipe so as to not allow air into the
probe. The exhaust of a car can pulse, especially at low RPM, drawing air in
causing bad readings, ensure the flexible probe is fully inserted and the clip
attached to the exhaust pipe.
4.6 Turning the pump ON/OFF
The analyzer is fitted with a pump to draw gas from the vehicle exhaust. To
conserve battery power, switch off the pump when you are not taking a
measurement. Gas values will not be displayed when the pump is turned off .
Use the key to turn ON and OFF the pump.

The analyzer will block readings while the pump is off and display ‘----‘ on all
gas channels.
It is recommended that the analyzer sample fresh air for 60 seconds before the
pump is turned off.
4.7 Regular Checks During Sampling
Care must be taken at all times not to exceed the analyzers operating
specifications, in particular ensure the following:-
• DO NOT PLACE THE ANALYSER IN THE ENGINE BAY.
• Do not expose the analyzer to temperatures outside its normal operating
range.
• DO NOT PLACE THE ANALYSER ON A HOT SURFACE.
• Ensure that liquid in the water trap does not go over the level indicator.
Note! The indicator only works while the trap is vertical. Water condenses
in the probe line and can quickly fill the water trap when the probe is
moved. Take care, watch the water trap closely and empty any water when
it is noticed.
• Make sure that the in-line particle filter is clean and does not become
blocked. If this filter is allowed to become dirty then damage may occur
inside the analyzer.
Check the following for water:
• Probe line, water trap and particle filter
When the blockage is cleared the analyzer should resume normal operation. If it
not possible to clear the problem then internal damage may have occurred and
the unit should be returned to a service center.
TIP: After testing hang the sample hose so that both ends are free to drain
any condensate.
4.8 Normal Shutdown Sequence
DO THIS EVERY TIME YOU USE THE ANALYSER
Page 31
AUTOplus manual
Page 31
Remove the probe from the vehicle exhaust - TAKE CARE ! THE PROBE
WILL BE HOT - and allow it to cool naturally. Do not immerse the probe in
water as this will be drawn into the analyzer and damage the pump and
sensors.
Once the probe is removed from the exhaust allow the readings to return to zero
and press the analyzer will count down from 30 to switch off.
OFF 30
MENU TO ESCAPE
12.52.30 am
26/04/12
If you have not finished but press by mistake, you can press to
return to normal operation and not switch OFF.
TIP: It’s a good idea to empty the water trap after testing so that the risk of
water getting on to the particle filter or into the analyzer is minimized.
Page 32
AUTOplus manual
Page 32
5. PRINTING INFORMATION – OPTIONAL EXTRA ONLY
Supplied as an accessory for the analyzer is an infrared thermal printer. Read
the manual supplied with the printer prior to operation. Connections to the
analyzer are detailed below:
• Infrared thermal printer - this does not require a cable to transmit the data
but uses an infrared (IR) link similar to a TV remote control. The IR emitter is
positioned on the top of the Analyzer and the bottom of the printer. Ensure
they are pointing at each other and within 300 mm, with no obstructions in the
way. Data may be lost if transmission is interrupted, a black square is
evidence of this. Keep the Analyzer pointing at the printer until the printout
has finished.
Data can either be printed from a ‘live’ test or from stored data.
5.1 Printing a ‘Live’ Test
During a vehicle test the Analyzer will print data on request. With the analyzer
showing the MAIN DISPLAY press and hold until the second bleep.
Current data will be sent to the printer. If the print button is held until the third
bleep, the test results will be printed in duplicate.
5.2 Standard Printout

6. MAINTENANCE
6.1 Emptying and Cleaning the In-line Water Trap
The in-line water trap should be checked and emptied on a regular basis. Water
vapor will condense and gather in the probe line. This may move suddenly to
the trap when the probe is moved. Care should be taken at all times.
Emptying of the water trap is detailed below :-
Water level indicator (do not exceed level while trap is vertical)
Carefully remove the end cap from the in-line housing. Dispose of the
condensate in a suitable drain. Clean the inside of the water trap using a soft
cloth
6.2 Changing the Particle Filter
This is a very important part of the analyzer and should be changed regularly. It
prevents dust and dirty particles entering the pump and sensors and hence
causing damage. The filter MUST be changed when it is discolored.
Remove the end cap from the in-line filter housing. Carefully remove the paper
filter element and dispose of it. Clean the inside of the filter housing with a
suitable soft cloth. Insert a new filter element onto the spigot in the filter housing
and carefully replace the end cap.
IF THE FILTER IS NOT CHANGED REGULARLY DAMAGE WILL OCCUR TO
THE SENSORS RESULTING IN A CHARGEABLE SERVICE. IT IS EVIDENT
Page 35
AUTOplus manual
Page 35
FROM AN INTERNAL INSPECTION OF THE ANALYSER IF THE FILTER HAS
BEEN CHANGED REGULARLY.
6.3 Cleaning
The body of the analyzer, its screen and rubber boot can be cleaned using a
damp clothe and standard household detergents. Wipe clean with a damped
cloth rinsed in water. Leave the analyzer in a warm place until all surface
moisture has evaporated and the analyzer is completely dry.
Under no circumstances should you use solvent-based cleaners as they can
cause blooming on the display and degradation of the plastic parts.
6.4 User Serviceable Parts
This product contains NO user serviceable parts. If problems occur seek advice
from your nearest approved service center.

soon as possible.
• The external particle filter is changed regularly.
• The analyzer is allowed to sample fresh air on a regular basis.
• The analyzer samples fresh air for 3 minutes before switch off.
• Do not blow smoke from a cigarette into the analyzer.
If you suspect the internal filter is blocked perform the following:
• Remove the probe connection from the water trap.
• Empty and clean the water trap with a dry cloth.
• Fit a new external particle filter.
• Run the analyzer in fresh air (pump ON) for at least one hour.
If the problem does not clear contact a service agent
8. ZERO CHECKS AND RE-CALIBRATION
During normal operation of the analyzer the following checks may be requested
as required:
• Zero setting of all sensors (can also be selected manually)
8.1 Zero setting

APPENDICES
A. MAIN DISPLAY PARAMETERS
The parameters and their meanings are detailed as follows: -
FUEL: The selected fuel will be displayed, i.e. PETROL.
• PETROL – Leaded or Unleaded petrol/gasoline.
• LPG – Liquid Petroleum Gas
• CNG – Compressed Natural Gas
• DIESEL
DATE : Analyzer date. See Set-Up menu to change.
TIME : Analyzer time. Use Set-Up menu to change.
BATTERY : Displays the battery level from 0-100%. During normal data
display operation the analyzer will show LOW BATTERY briefly at
intervals of about 45 seconds for less than 30% of charge. The
analyzer will turn off if less than 10% charge is detected. With the
charger connected the display will read close to 100%.
Note: Allowing the battery to discharge fully may destroy it.
O2 : Oxygen measured in the exhaust gas indicated in percentage %.
With the pump off the analyzer will display - - - -. If there is a fault
with the oxygen sensor then FLT will be displayed.
CO : Carbon monoxide measured in the exhaust gas indicated in
percentage %. With the pump off the analyzer will display - - - -. If
there is a fault with the CO reading then FLT will be displayed.
CO2 : Carbon dioxide measured in the exhaust gas in percentage %.
With the pump off the analyzer will display - - - -. If there is a fault
with the CO2 reading then FLT will be displayed.
HC : Hydrocarbons measured in the exhaust gas indicated in ppm
(parts per million) n-hexane (petrol). With the pump off the
analyzer will display - - - -. If there is a fault with the HC reading
then FLT will be displayed.

COK : Generally known as corrected CO. This value is calculated and
used for comparison with the actual infrared measured CO value.
COK = (COx15)/(CO + CO2), for normal car exhaust CO + CO2 =
about 15%. In this case CO is approximately equal to COK. If
COK is clearly higher than CO this indicates defects such as
exhaust leaks. At near zero COK is not valid.
LAMBDA (λ): The value of Lambda gives an indication of the burning
fficiency of the engine. This can be replaced with the Air Fuel
Ratio (AFR) below. See section 5.2.3.to change between displays.
Appendix B gives the formula used.
When sampling fresh air and lambda is outside operation range
this indication will show ‘-----‘.
AFR : Air Fuel Ratio is another method for displaying the efficiency of an
engine. The calculation for the AFR is Lambda multiplied by 14.7
for Petrol and 15.6 for LPG (typically). When sampling fresh air
this indication will show ‘-----‘.
NO : Nitric oxide reading in ppm (parts per millions) of the exhaust gas.
Displayed when Nitric oxide sensor fitted, indicated on the rear
label. Displays NOT FITTED or N/F when sensor not fitted and
FAULT or FLT if failed.
NOx : A calculated value based on the measured level of Nitric Oxide to
display total oxides of Nitrogen. NOx = NO X 1.05
TIME TO: The analyzer requires to regularly zero the sensors. Once a ZERO
has been performed the time to the next zero is displayed in
minutes. Check there is sufficient time remaining before starting
a test and perform a manual zero if not.

B. LAMBDA CALCULATION
The value for Lambda is a determinant for the burning efficiency of an engine.
The value depends on the composition of the fuel, the air that is used for the
combustion and on the combustion products as found in the exhaust gases.
A basic formula, taking into account:
• Components of the fuel: carbon, hydrogen, oxygen and water content;
• Water content of the air;
• Components of the exhaust gases: carbon dioxide, carbon monoxide,
hydrocarbons and nitrogen oxide;
has been developed by J. Brettschneider and published in Bosh Technishe
Berichte, Volume 6 (1979), No. 4, page 177-186.
A simplified formula, derived from the basic formula, and based upon the
assumption that the water content of the fuel and air and the NOx content in the
exhaust gases are negligible, allows the computation of Lambda when certain
components of the exhaust are measured.
B.1 Oxygen balance formula
For Lambda calculation, based upon measurements of CO, CO2, HC and O2, the
following formula is standardized: Displayed on the analyzer as LAMBDA (O)
λ = CO2 + (CO/2) + O2 + [HCV/4 × {3.5 / (3.5 + CO/CO2)} – OCV/2] × (CO2 + CO)
(1 + HCV/4 - OCV/2) × {(CO2 + CO) + (K1 × HC)}
Where:
CO = Carbon monoxide % volume measured.
CO2 = Carbon dioxide % volume measured.
HC = Hydrocarbon ppm volume measured.
O2 = Oxygen % volume measured.
K1 = Conversion factor for HC is expressed in ppm vol n-hexane (C6H14)
equivalent. Its value in this formula is 6.10-4
Hcv = Atomic ratio hydrogen to carbon in the fuel. Nominal value is 1.7261
Ocv = Atomic ratio oxygen to carbon in the fuel. Nominal value is 0.0176
