2.3 Equipment Overview
A
Mirror
The headlight tester is aligned with the vehicle by using
the movable alignment mirror. The optional laser aligner
is integrated in the mirror holder.
B
Column
The column envelopes a precision profile which carries
the slide rails. The counterweight which can be used to
set the housing to the desired test height is located in
the interior of the column (automatic locking).
C
Carriage (with
Spirit Level)
The carriage of the headlight tester either runs on two
rails when it is in a fixed location or it is equipped with
rubber rollers.
D
Knob for
Folding Mirror
The projection screen in the housing can be observed in
the folding mirror.
E
Viewing
Window
The projection screen in the housing can be viewed
through the viewing window.

F
Light Measure-
ment Unit
The light intensity or illuminance of the headlights can
be checked using the light measurement unit.
G
Setting Dial
Use the setting dial to move the projection screen up
and down in the housing to achieve the desired
inclination value.
2.4 Projection Screen
The projection screen is based on the test condition that the distance between
headlight and test surface is 10 m.
Use the folding mirror or the viewing window to observe the projection screen in
the housing on which the headlight beam is reproduced.
The image on the projection screen is displayed 20 times smaller than the origi-
nal.

Dividing line = Reference axis for light-dark border of low beam
B1
Tolerance mark (left) for inflection point of asymmetrical European low
beams
B2
Tolerance mark (right) for inflection point of asymmetrical European low
beams
C
Central mark = Elementary point for setting the high beams
D
The outlined corners indicate the size of the test surface which is
binding based on the directives for vehicle headlight settings (e.g. in
Germany).

8BA380801-en
2.5 Setting Wheel
Use the setting wheel to move the projection screen up or down in the housing.
As the inclination of the headlight hot spot in relation to the driving surface is
usually expressed in percentage, the setting wheel has a percentage (%) dial.
The inclination values (light-dark border of the vehicle headlights) can be set
from 0 to -6 % using the dial.

BA380801-en 9
2.6 Definition of Technical Terms
2.6.1 Pitch Angle
Angle of inclination of light-dark limit against the test surface.
The inclination of headlight lighting bundle against the test surface is expressed
as a percentage, using 10 m as a reference parameter:
1000
hH −
X 100
2.6.2 Low Beam

10 BA380801-en
A
Light-dark limit
Boundary for light distribution between ‘top dark’ and ‘bottom light’ for
low-beam lights.
B
Inflection point
Synonymous with the light-dark limit for asymmetric low-beam lighting.
The deviation of the inflection point is expressed in %. 10 meters is used
as the reference dimension.
α
Yaw angle
Angle between the inflection point on the rising component of the light-
dark limit and the horizontal line for asymmetric low-beam light.
β
Rolling angle
Angle between the left component of the light-dark limit and the
horizontal, usually 0°.
2.6.3 High Beam
C
Central mark
From the central mark, the deviation of hot-spot is specified in X and Y
directions.
D
Hot spot
Center of light beam for high-beam. The deviation of hot spot from central
mark is expressed in %.10 meters is used as the reference dimension.

3Operation
3.1 Aligning
When using guide rails, position the device centrally in front of the vehicle.
Without guide rails, the device must be adjusted in front of each headlight.
Please observe your national guidelines and specifications.
The device is correctly aligned when two symmetrical reference points on the
front of the vehicle are located on the black line of the alignment mirror.
3.1.1 Laser Alignment Unit (Option)
The optional unit is integrated into the mirror holder. The device is correctly
aligned when the laser pointer is parallel to two symmetrical reference points
on the front of the vehicle.
Observe manufacturer’s instructions according to workshop manual.
CAUTION
Never look into the laser beam (laser class 2M). Comply with work safety and
accident prevention directives (H&SW regulations) in respect of laser radiation.
The AA Mignon batteries powering the laser are located in the alignment unit
and can be easily replaced.

12 BA380801-en
3.2 Setting the Headlights
1 Switch on the headlights.
2 Set the projection screen to the required inclination value using the setting
dial.
3 The headlights should be tested individually, the other(s) should be turned
off or covered if necessary.
4 Observe the projection screen. If the headlight setting is checked through
the folding mirror, note that all screen markings are displayed mirror-
inverted.
5 Adjust the headlights until they match the applicable statutory directives.
Example: When setting the low beam, the dividing line is the reference line for
the inclination point of the light-dark border.

BA380801-en 13
3.3 Measuring the Luminous Intensity / Illuminance
Light intensity or illuminance of low and high beams is indicated in Lux (lx) and
Kilocandela (kCd) by the light measuring unit.
Adhere to the following rules in order to get correct test results:
•The headlight tester must be aligned with the headlight
•The headlights must be set correctly
•The vehicle battery must be fully charged
•The vehicle engine should be idling at an average RPM
3.3.1 Low Beam
1 Switch on the low beams.
2 Position the toggle switch to low beam position (upwards).
3 Set the projection screen using the dial so that the dividing line lies on the
light-dark border.
4 Read the value: The incoming light is extrapolated to 25 m and can be read
off the upper scale.
3.3.2 High Beam
1 Switch on the low beams.
2 Set the projection screen using the dial so that the dividing line lies on the
light-dark border of the low beams.
3 Switch on the high beams.
4 Position the toggle switch to high beam position (downwards).
5 Read the value: The incoming light is extrapolated to 25 m and can be read
off the lower scale.

14 BA380801-en
4Maintenance
This headlight tester is an optical measuring device and must therefore be han-
dled accordingly (i.e. with care).
The lens needs to be wiped regularly with a clean cloth and commercial glass
cleaner. In all other respects, this is a zero-maintenance device.
