Please read the standard operating procedures and user’s manual thoroughly and carefully
before commissioning the machinery and comply with the instructions. The operating manual
should always be conveniently stored to be readily available at all times.
This operating manual is an addition to the operating manual for the testing lane Eurosystem.
All safety instructions provided in chapter 1 of these operating instructions must be complied
with.
Injury to persons incurred due to non-compliance with these operating instructions are not
covered by the product liability regulations.
MAHA is not liable for damage to the test stand and/or vehicles incurred due to non-compliance
with these operating instructions.
A warning means that instructions that are not complied with or incompletely complied with can
endanger persons.
Attention means that instructions that are not complied with or incompletely complied with can
lead to equipment damage.
Notes provide additional information.
Safety information is provided to warn about dangerous situations and help prevent damage to
equipment and injury to persons. For your own safety it is imperative that all safety regulations
included in these instructions be carefully observed.

2 Description
2.1 Usage, Range of Application
The speedometer tester is a roller tester for the inspection of the speedometer function of
vehicles. The speedometer tester permits the measurement of speed deviation as well as the
deviation of the mileage meter.
Passenger cars and transporters up to a total axle load of 4 t can be tested (2 t with TPS III for
motorcycles).
The recorded measuring values are transmitted to the Eurosystem communication desk and
then displayed on the screen. The storing and the reviewing of measurements is described in
the operating manual for the testing lane Eurosystem.
2.2 Installation
The test stand may only be installed and commissioned by the manufacturer's trained
authorized personnel or other qualified technicians of MAHA dealers or representatives. MAHA
instructions must be followed when installing or expanding the testing device.
The manufacturers CE conformity declaration becomes invalid when the installation is done by
qualified service technicians. MAHA is not liable for damage caused by unqualified,
unauthorized installation. Further, the manufacturers warranty also becomes invalid.
2.3 Noise Emission
The noise emission test was conducted during the speedometer test, at the highest test speed
of 150 km/h.
Test results
A-evaluated sound pressure level: 105,0 dB(A) (averaged with all measuring points, see
measuring protocol)
A-evaluated acoustic power level: 103,4 dB(A) (calculation based on DIN 45635 Part 1)
Due to the high noise in the test room, ear protection should be worn.

3 Operations
3.1 Introduction
Please also read chapter 4, Eurosystem PC-Program, in the operating manual for the testing
lane Eurosystem.
The second part of this chapter describes the testing procedure of a speedometer test and
distance test. The screen pictures on the right-hand side show the screens which appear during
operation. The steps listed on the left provide the user with clear explanations of procedure.
The third part provide information about the operation of a TPS I test stand with self-contained
drive (Option). The fourth part describes the operation of the TPS III (motorcycle).
The storing and the reviewing of measurements is described in the operating manual for the
testing lane Eurosystem.
3.2 Testing Procedure
In order to start the testing procedure, the
monitor must show the main menu.
The instruction line must show the following
message:
New test can begin ...
If this message does not appear press
<F8 NEW VEHICLE>.
Now the test lane is ready for a vehicle to be
driven on. When the vehicle drives onto the
individual equipment the corresponding test
screen is blended in.
Always pay attention to the messages and instructions on the instruction line during testing.
(in the description this is indicated by Instruction text).
The recorded measurement values are automatically taken over in the temporary memory and
remain there until they are stored in connection with customer/vehicle or until they are
overwritten when a new test is conducted.
The following guides the user through the automatic testing procedure step by step. Usage of
the individual screen elements and the keyboard has already been clearly explained. See the
following sections in the operating manual for the testing lane Eurosystem to refresh your
memory:
=> 4.1.3 Screen Design
=> 4.1.4 Keyboard Usage

3.2.1 Speedometer Test
No vehicle with 4 wheel drive or automatic transmission may be tested on the speedometer
tester. This can lead to damage on both the vehicle and the test lane. Should questions arise
inquire at the responsible service representative.
The speedometer test can be conducted by using the keyboard or the remote control. If a
remote control is not available, a second person will be needed to perform the test.
The speedometer tester permits the measurement of the difference between the actual vehicle
speed and the speed displayed on the tachometer of the vehicle.
1 Drive onto the test stand
a. Drive the driven axle of the vehicle
slowly onto the roller set.
The vehicle must be positioned
straight and centered on the roller
set.
b. Apply the parking brake.
2 Preparations
Secure the vehicle with tightening belts
(see chapter 2).
3 Start the testing program
Accelerate the vehicle up to 5 km/h to
start the testing program.
Rotating test stand rollers are potentially dangerous! Risk of injury!
=> The following screen appears:
Accelerate the vehicle to the target value
The peak of the green arrow indicates the
target speed, the bottom indicates the
tolerance range (5 km/h). The black arrow
shows the actual speed of the vehicle.
4 Conduct the test
Accelerate the vehicle up to the indicated
target value as per vehicle speedometer.
The recorded test values will be
displayed. If the actual speed is within the
tolerance range for 3 sec., the test values
will automatically be stored.
The next target speed will be indicated.

TPS I and III for Eurosystem Operations
D1 1004BA1-GB03 9
The measuring value can also be stored by pressing the <F5> key, in order to display the next
target speed. If a remote control is not available, a second person is needed to store the value
by using the keyboard.
5 Repeat test
The test must be repeated for every
target speed as described in step 4.
The test can be aborted by pressing the
<ESC>-key.
