Requirements for meters
1.1 Meters are devices, which, depending on the characteristics of the
the vehicle in which they are installed, and the rates in them
have been set up, automatically calculated and displayed on an ongoing basis, if they are
in operation, the amount that the customer has a vehicle marked taxi
pay based on the distance travelled and at a speed lower than the
threshold, based on elapsed time of the car rental duration, excluding
various supplements, which may result from legislation in force in
the Member States.
1.2 Special terms
Data display meter depend upon redemption of any rates on
the constant "k" of the taximeter and the constant "w" of the vehicle, in which the
the meter is installed. This constant "w" is a function of the effective circumference "u"
the wheels of the vehicle and the ratio of the number of revolutions of the wheels to the number of revolutions of the part of the vehicle
used to link a metered taxi vehicles.
1.2.1. Constant "k" of the taximeter
The constant "k" of the taximeter is characterized by a quantity that indicates the type of
and the number of pulses that the instrument must accept in order to provide
the correct value data corresponding to a given distance travelled.
This constant "k" is expressed:
and as the number of rotations) per one kilometre
(b)) as the number of pulses per one kilometre
Depending on whether the information relating to the distance travelled
the vehicle is fed into the taximeter as its main shaft speed
(the drive shaft in the entry point into the device), or in the form
1.2.2 Constant vehicle "w"
The "w" of the vehicle constant is a quantity indicating the type and number of pulses
intended for the propulsion of the taximeter and that show in the appropriate device,
which is the vehicle for this purpose, and the corresponding distance
This constant "w" is expressed:
and as the number of rotations) per one kilometre
(b)) as the number of pulses per one kilometre
Depending on whether the information about the distance travelled by the vehicle is given by
the number of revolutions of the part driving the taximeter or whether it is given by the number of
This constant change depending on several factors, in particular
in air pressure and wear and tear on the payload of the vehicle
and on the conditions under which the ride is in progress. This constant must be determined
under normal test conditions for the vehicle (1.2.7).
1.2.3. Effective circumference "u" of the wheels
Effective circumference "u" of the wheels of the vehicle, which drives the taximeter directly or
indirectly, the distance travelled by the vehicle during one of the total rotation
This round. If the meter is powered by two wheels together, is effective
circuit, expressed in millimetres of the effective diameter of the two circuits
Effective circumference "u" is in a relationship with a constant "w" of the vehicle (point 1.2.2) and the
This circuit must, if it is necessary to specify, provide for
the conditions referred to in point 1.2.7.
1.2.4. the adjustment device
The purpose of the adjustment device is to modify the constant "w" of the vehicle on the
the constant "k" of the taximeter.
1.2.5. Range of permissible errors
Range of permissible errors mentioned in item 5 only depends on the device
itself (errors). The actual value (point 5) used for
determination of errors are calculated from the constant "k" of the taximeter and rates
were in the taxi meter set.
Range of permissible errors determines the maximum deviation between the largest and
the smallest indications.
1.2.6. Changeover speed
Changeover speed is the speed at which the drive of the indicating device
the taximeter changes of mode of calculation by counting elapsed time mode
the calculation by counting the distance travelled, and vice versa.
This speed is obtained by dividing the "time" rates the rate of "distance".
1.2.7. Normal test conditions for the vehicle (for determining its
"Normal test conditions for the vehicle" are obtained, if:
a) tyres fitted to the wheel or wheels driving the taximeter are
of a type which has the same effective circumference "u", such as the wheels,
that are used for determination of the constants of the "w".
(b)) these tires must be in good condition and must be inflated to the
the correct pressure;
(c)), the load carried by the vehicle is approximately 150 kg. (According To the
the Convention corresponds to the weight of two adult persons, one of them is
(d)) the vehicle is moving under its own power in a straight line after
a level surface, at a speed (40 +/-5) km/h.
If these tests are carried out under different conditions, e.g.. with different
weights, different speeds or speed step, on the test
stand, etc., then the results are adjusted by the conversion factor
necessary to convert these values to the values that would provide for the
the above "normal test conditions".
THE UNIT OF MEASUREMENT
For information provided or displayed by taximeters are allowed only
the following units of measurement:
-metre or kilometre, for distance.
-Second, minute, or hour, for the last time.
The fare must be expressed in legal units.
3.1 measuring devices and calculated device
3.1.1. The taximeter must be constructed in such a way that it calculates and
show the amount of the fare solely on the basis of:
a) distance travelled (distance-based drive distances), if
the vehicle moving at a speed greater than the changeover speed;
(b)) time (elapsed time-driven drive) when the vehicle is moving
at a rate less than the changeover speed or has stopped.
3.1.2 the distance-based Drive must be effected by distance wheels, reversing
vehicles, however, must not cause a reduction in the value of the fare, or shown
the distance travelled.
Drive past the time driven must be effected by time, which may
be activated only a control device of the taximeter.
If the mechanical timekeeping manually wound, then it must work
at least eight hours without stretching or two hours if there is a
cocking system associated with each manual activities that precedes the
start of the taximeter.
If the mechanical timekeeping electrically wound, then it must be
How to auto.
The electrical timekeeping movement must be ready for action all the time.
3.1.3 distance-distance drive must each time settings
the first change of indication must take place rates until after the initial
distance is determined by the regulation of rates. Subsequent changes to the

The drive past the time when each of the tariffs
the first change of indication must take place after the expiry of the initial term, which in
each Member State shall determine in accordance with the regulation on tariffs. Subsequent changes to
the indicator must correspond the same time intervals.
Without any changes to the substance of the actuator must be the ratio between the initial
distances and subsequent intervals of distance is the same as the ratio between the
the initial period and subsequent time intervals regardless of
3.1.4 the adjusting device shall be so designed that after opening
the cover was not able to gain access to other parts of the taximeter.

time must not lead to the device indicating the value of the fare which
is to be paid;
c) indicator indicating possible supplements (3.3.7) must be

(b)) to the operating position "FARE", which shows the final amount
to pay, without any extra charge. In this position, the actuator must be
elapsed time-driven and drive the distance-the distance
plugged in at a rate that is allowed in each Member State by the competent
Regulation of rates.
3.2.4. The function of the control device
The functionality of the device is subject to the following restrictions:
starting from any) operating position at any rate must not be
possible to return the taximeter to the operating position "for hire", without passing
through the "stopped" position. The transition from one tariff to another must, however,
still be possible;
(b)), starting from the "stopped" position must not be possible to return
the taximeter to the operating position at any tariff without passing through the
"for hire" position;
