Instructions for your personal safety and for the protection of
equipment/vehicle components
Mains voltages
Danger of acid burning
in the respiratory system
High voltage
Hazardous voltages occur in both the lighting system and the
electrical system of a motor vehicle. If contact is made with live
parts (e.g. with the ignition coil), there is a risk of electric shock
from flashover voltages caused by damaged insulation (e.g.
ignition cables which have been attacked by martens). This
applies to both the primary side and the secondary side of the
ignition system, to the cable harness and the plug connections, to
the lighting systems (Litronic) and to the tester connections.
When exhaust gas measurements are taken, the sampling hoses which are used release a highly caustic gas
(hydrogen fluoride) that can cause acid burning in the respiratory
system when heated to temperatures in excess of 250 °C (482
°F) or in the event of fire.
Safety precautions:
- All testers must be connected to properly grounded, shockproof sockets.
- Testers must always be connected using the power cables
supplied with them.
- All extension cables must be fitted with shock-proof contacts.
- Any cables with damaged insulation must be replaced (e.g.
power or ignition cables).
- Connect testers to the lighting system and switch them on
before connecting them to the vehicle.
- Connect testers to the engine ground or to the battery (B-)
before switching on the ignition.
- Always switch off the ignition before performing any work on
the electrical system of the vehicle. The term "work" includes
connecting testers, replacing parts of the ignition system,
removing assemblies (e.g. generators), connecting assemblies
to a test bench, etc.
- Wherever possible, tests and settings should always be carried
out with the ignition switched off and the engine stationary.
- If tests or settings are carried out with the ignition switched on
or the engine running, care must be taken not to touch any live
parts. This applies to all the connecting cables of the testers as
well as to the connections of any assemblies at the test bench.
- Test connections must always be made using suitable connectors (e.g. Set of Test Cables 1 687 011 208 or vehicle-specific
adapter cables).
- Make sure that all test connections are properly plugged in and
secure.
- Never open the casing of the screen.
- Always wear gloves made of neoprene or PVC
when removing combustion residues.
Safety precautions:
- Consult a doctor immediately after inhaling!
- Neutralize any residues left after a fire with a calcium hydroxide
solution. This produces non-toxic calcium fluoride, which can
be washed away.
Danger of acid burning
Acids and alkalis can cause severe burning on unprotected
skin. Hydrogen fluoride forms hydrofluoric acid in combination
with moisture (water).
The condensate which accumulates in the sampling hose and
in the condensate container likewise contains acid.
When replacing the O2 sensor, it should be remembered that it
contains alkali.
Safety precautions:
- Rinse any affected parts of the skin immediately in water, then
consult a doctor!
- The O2 sensor is a hazardous waste and must be disposed
accordingly. Bosch technical equipment suppliers are able to
dispose of the sensors O2 in the appropriate manner.
If liquid crystal escapes from a damaged liquid crystal display,
it is imperative to avoid direct contact between the liquid and the
skin, as well as inhalation or swallowing!
Safety precautions:
- Wash the skin and clothing thoroughly with soap and water if
it comes into contact with liquid crystal.
- Consult a doctor immediately after inhaling or swallowing liquid
crystal.

Instructions for your personal safety and for the protection of
equipment/vehicle components
Danger of asphyxiation
Car exhaust fumes contain carbon monoxide (CO) - a colorless,
odorless gas. If inhaled, carbon monoxide causes an oxygen
deficiency in the body. Extreme caution is therefore essential
when working in a pit, as some of the components of the exhaust
gas are heavier than air and settle at the bottom of the pit.
Caution is also necessary when working on LPG-driven vehicles.
Safety precautions:
- Always ensure effective ventilation and suction (especially
when working in a pit).
- Always switch on and connect the suction plant in a closed
area.
Danger of burning
When working on a hot engine, there is a risk of injury from
burning if such components as the exhaust gas manifold, the
turbocharger, the Lambda sensor, etc. are touched or if parts of
the body come too close to them. These components may be
heated to temperatures of several hundred degrees Celsius.
Depending on the duration of the exhaust gas measurements, the
sampling probe of the exhaust gas measuring instrument may
also become extremely hot.
Safety precautions:
- Always wear protective clothing, e.g. gloves.
- Allow the engine to cool down first (this also applies to auxiliary
heating systems).
- Keep the tester connecting cables well away from all hot parts.
- Do not leave the engine running any longer than necessary for
the test or setting.
Danger of injury
Noise
Danger of crushing
If the vehicle is not prevented from rolling away, there is a danger
of people being crushed against a workbench, for example. Both
running and stationary engines have rotating and moving parts
(e.g. belt drives) which may cause injuries to fingers and arms. A
special hazard is presented by electrically driven fans, in that they
may be switched on without warning while the engine is stationary
and the ignition is switched off.
There is a danger of tripping over the protruding rollers, the
connecting cables and the power cable of the test system.
Do not place heavy objects on or lean on the sensor holder,
because there is a danger of it breaking and falling on your feet.
Noise levels in excess of 70 dB(A) can occur when measurements
are carried out on a vehicle, especially at high engine speeds.
Damage to hearing may result if human beings are exposed to
noise at such levels over an extended period of time.
Safety precautions:
- If necessary, noise protection facilities must be provided by the
owner at all workplaces in the vicinity of the testing area.
- If necessary, suitable personal noise protection facilities must
be used by the operator.
Safety precautions:
- Take steps to prevent the vehicle from rolling away while it is
being tested.
Select the park position if the vehicle has an automatic transmission and apply the handbrake or lock the wheels with
chocks (wedges).
- Keep well away from rotating/moving parts while the engine is
running.
- When working on or in the vicinity of electrically driven fans,
allow the engine to cool down first, then disconnect the plug of
the fan motor.
- Keep the tester connecting cables well away from all rotating
parts.
- Lock the brakes on the test system trolley so that it cannot roll
away.
- Lay the connecting cables in such a way that no-one can trip
over them.
- Do not place heavy objects on or lean on the sensor holder.

2.4 RPM measurement
The engine and ignition must always be switched off
before any work is carried out on the ignition system.
Before performing RPM measurement (engine-speed
measurement), always connect the B- clamp of the
battery connecting cable (B+/B-) to vehicle earth.
Preparing the measuring point:
- The clearance between the clip-on sensor and the next bend in
the tubing must be at least 10 mm.
- Clean the clamping point in a straight section of the injection
tubing using sandpaper.
- The metal at the clamping point must be bare and must be
totally smooth (no dents etc.). Remove the insulation from
around insulated injection tubing.
Connecting to the vehicle:
- Determine the diameter of the injection tubing and select an
appropriate clip-on sensor. The standard clip-on sensor
KG6 (6 mm) is enclosed. If the car in question has injection
tubes with a different diameter, your can order appropriate
clip-on sensors (available as special accessories).
- Connect the clip-on sensor to the connecting cable (blade
receptacle).
i Only ever connect one engine-speed sensor. The system
automatically selects the engine-speed sensor connected.
- Connect the black clamp of the connecting cable to vehicle
earth.
Set the number of pulses and cylinders in accordance with
the source used for picking up the engine speed (RPM).
! Only use a clip-on sensor that matches the diameter of the
injection tubing.
2.4.1 The clip-on sensor
● Measuring point
i Clip-on sensors are wearing parts.
! The points listed below must always be observed when
handling clip-on sensors, so that damage to the foil in the clipon sensor and therefore failures can be avoided and the
service life of the pickup can be extended.
A
>10
mm
B
- The clip-on sensor must not be rotated after being clamped
with the securing clip.
- Only use a clip-on sensor that matches the diameter of the
injection tubing. If the diameter of the clip-on sensor is too
large, it is not possible to measure the engine speed (RPM).
If the diameter of the clip-on is too small, the pickup may be
irreparably damaged.
- Never use emery paper or other tools to clean the clip-on
sensor.
Connecting to the Emission Analysis Measuring Instrument:
- Connect the clip-on sensor connecting cable to plug-in socket
2 of the Emission Analysis Measuring Instrument (see
Description of the unit).
- Connect the Emission Analysis Measuring Instrument (plugin socket 1, see Description of the unit) to vehicle earth using
clamp B- of the battery connecting cable (B+/B-) in order to
achieve equipotential bonding during RPM measurement
(engine-speed measurement).
8
459331/1P
- The clamping point must be perfectly smooth.
If the injection tubing is too thin, clamp the clip to the
next metal part available.
i The clip-on sensor must not be rotated around the
injection tubing after being clamped. The clip-on sensor
must be clamped onto the injection tubing in such a way
that it does not make contact with any other components
(wires, hoses, engine etc.).
- Clamp the clip-on sensor onto the cleaned section of
injection tubing as shown in the figure.
When making the connection, injection tubing level A must
flush with the the switching surface (level B) of the clip-on
sensor.
● Number of pulses
The number of pulses used for RPM measurement (engine-speed
measurement) using a clip-on sensor depends upon the type of
engine. The number of pulses must be set accordingly:
- with a 4-stroke engine, 1 pulse
- with a 2-stroke engine, 2 pulses
2.4.4 RPM measurement (engine-speed measurement) by
means of alternator residual ripple (battery connecting
cable B+/B)
The battery connecting cable (B+/B-) is used to measure the
engine speed (RPM) of compression-ignition (diesel) engines
by means of the vehicle electrical system.
● Functional description
2.4.2 The TDC sensor
● Measuring point
If the vehicle manufacturer has installed a TDC sensor in the
vehicle or there is a hole provided for fixing the workshop TDC
sensor to be used, RPM measurement (engine-speed measurement) can be carried out using this sensor.
The engine speed (RPM) is measured by evaluating the residual
ripple of the alternator output voltage. This signal is, however,
superimposed by interference. To be able to detect the useful
signal amongst this interference, an adaptation phase of approx.
15 to 30 seconds is required before the measurement phase.
● Measuring procedure
- Connect the vehicle-specific TDC-sensor connecting cable to
plug-in socket 3 of the Emission Analysis Measuring Instrument
(see Description of the unit) and to the vehicle.
● Number of marks
The number of pulses used for RPM measurement (engine-speed
measurement) using a TDC sensor depends upon the type of
TDC-sensor system.
You must know how many pins or notches there per 360° rotation
of the crankshaft.
- Switch off the engine.
- Using the battery connecting cable (B+/B-), connect the VSM
(plug-in socket 1, see Description of the unit) to the vehicle
battery. The battery connecting cable is protected against
polarity reversal.
i When working on a 24-V vehicle electrical system, connect
to 24V! Do not connect the VSM just to one of the 2 batteries.
The voltage range is from 9 to 32 V. When working on a
vehicle with a number of independent batteries (e.g. a
camping bus), connect the battery connecting cable (B+/B-) to
the battery that is charged directly by the vehicle alternator.
- Set the number of cylinders accordingly.
2.4.3 The RIV sensor
● Measuring point
- Connect the RIV sensor to the injection pump.
- Connect the connecting cable of the RIV sensor to plug-in
socket 2 of the Emission Analysis Measuring Instrument
instead of the clip-on sensor connecting cable (see
Description of the unit).
- Start the engine and accelerate briefly so that the charge
indicator lamp in the vehicle goes out.
i Switch on the vehicle lights and if fitted the rear heated
window.
Switch off the blower and other consumers.
- Leave the engine running at idle speed.
- The engine speed (RPM) measured can be checked in the
"Engine preconditioning and prechecks" test step.
● Number of pulses
The number of pulses used for RPM measurement (engine-speed
measurement) using an RIV sensor depends upon the type of
engine. The number of pulses must be set accordingly:
- for 4-stroke engines: pulse number 1
- for 2-stroke engines: pulse number 2
The engine speed (RPM) measured is displayed after approx.
15 to 30 seconds.
i If RPM measurement (engine-speed measurement) does not
result in a value being displayed, first check whether the
polarity of the connections is correct.
You can now perform a test rev-up.
i The engine must be at normal operating temperature!
When performing the test rev-up, watch the breakaway speed. If
the breakaway speed displayed is plausible and stable,the engine
speed (RPM) measured by means of the alternator’s residual
ripple is correct. If not, you must choose a different method of
measuring the engine speed (RPM).

To measure the engine speed (RPM), you must select the correct
number of pulses and cylinders to match the engine being tested.
This enables the rotational speed of the engine-speed sensor
connected to be identified. For details, see section 2.4, RPM
measurement (engine-speed measurement).
Before performing RPM measurement (engine-speed
measurement), always connect the B- clamp of the
battery connecting cable (B+/B-) to vehicle earth.

● Measuring the breakaway speed
With category A and oil temperature more than 60 °C it is possible
to skip oil temperature input by pressing ENT.
This measuring step is not obligatory and can be skipped by
pressing ENT.
● Bringing the engine up to normal operating temperature
Starting from idle speed, accelerate the engine carefully up to
breakaway speed.
! If the engine is not brought up to the specified operating
temperature, there is a danger of it being damaged by
carrying out the exhaust-gas analysis test. Apart from that, all
the measured values subsequently gained may possibly be
incorrect.
To check that the engine temperature has reached the specified
value, use the oil-temperature sensor to measure the
oil temperature (prescribed only for category A vehicles).
- Connect the oil-temperature sensor to plug-in socket 5 of the
VSM.
! To avoid damaging the engine, accelerate the engine
slowly up to breakaway speed. If the max. tolerance is
exceeded, abort the procedure immediately!
The breakaway speed is now measured over a period of
3 seconds and a mean value is calculated.
If the breakaway speed is o.k., confirm it by pressing ENT. The
rev-up measurement is then started automatically.
If the breakaway speed is not o.k., confirm this by pressing the
cursor keys z and v , and then press ENT.
The message "EXHAUST-GAS ANALYSIS TEST NOT PASSED"
appears in the display.

In the "DIAGNOSIS" menu, you have the choice of two types of
measurement: "CONTINUOUS MEASUREMENT" and "FREE
ACCELERATION".
Use the cursor keys z and v to make your selection and
confirm it by pressing ENT.
4.1 Continuous measurement
Procedure:
- Connect the engine-speed sensor to the vehicle.
- Start the engine and if necessary warm it up.
- Insert the exhaust-gas probe into the exhaust pipe and make
sure it is seated securely.
Caution! Hot probe!
The exhaust-gas probe may still be very hot from being
used beforehand for testing a different vehicle.
You then select the number of pulses and cylinders (proceed
as described in the passage "Selecting the number of pulses
and cylinders" in section 3.3 "Engine preconditioning and
prechecks").
The current engine speed (RPM) is also displayed at the same
time.
After selecting, confirm the inputs by pressing ENT.
You can now carry out up to 25 measurement rev-ups at different
engine speeds (RPM).
Once the engine has reached the desired speed, press the # key
to store the measured value. The measurement is then stopped
by pressing ESC.
Using the cursor keys z and v , you can then display or print out
the measured values or end continuous measurement completely.
Confirm your selection by pressing ENT.
4.2 Free acceleration
This procedure is used to measure the exhaust-gas values, e.g.
when adjusting the engine. The k values are not evaluated and no
purging rev-ups are carried out.
A maximum of 16 measurement rev-ups can be carried out.
If you want to stop carrying out measurement rev-ups before you
reach 10 times, press ESC or ignore the "FULL THROTTLE"
prompt (i.e. do not rev up the engine); the program will then detect
time-out after a specified delay has elapsed.
At the end of the measurements, you can use the cursor keys
z and v to display or print out the measured values, print out
curves which show the opacity and engine-speed values plotted
against time, or end this type of measurement completely.
Confirm your selection by pressing ENT.

10. Maintenance
The measured opacity value must be between 45 % and 55 % or
1.40 m-1 and 1.80 m-1. If a measured value is displayed that is not
within this tolerance, the RTM opacimeter must be serviced inhouse (see Operating Instructions RTM 430 AT-PR UBF 956/1,
Part Number 1 689 979 651).
After servicing, the check using the calibrating pen must be
repeated.
If servicing does not lead to the desired effect, contact your
Bosch After-Sales Service representative.
