3 Delivery of device
3.1 Damages during carriage
At the receipt of the goods, check for any visible damages at the outer packing. If it
is unharmed you can sign the receipt of the documents. If you do suspect by your
visual impression that damage has occurred, make a note of the visible damage on
the delivery receipt or freight papers and get the carrier to countersign it.
Moreover, the courier service must be held responsible for the damage in writing.
If a hidden damage is discovered while unpacking, you have to inform and hold the
courier service immediately liable in the following way: “When opening the parcel
we had to notice that … etc.“ This superficial checking of the goods has to be done
within the time limit set by the courier service, which is normally 7 days. However,
the period could be less. Hence, it is recommended to check the exact time limit
when receiving the goods.
If there are any damages also inform your authorized Zehntner agent or Zehntner
GmbH Testing Instruments immediately.
3. Shipment
In case the device needs to be transported again at a later time, it has to be
packaged properly. If the device was supplied in a carrying case or storage box, this
original packaging needs to be used also for later shipments. Additionally put filling
material into a cardboard box in order to protect the device of shock during
carriage.

5 Inserting comparison standards
After opening the device cover (4) you will see the accessory drawer, where the
comparison standards can be stored. By default, 4 comparison standards can be
stored. If needed, the storage capacity can be enlarged by Zehntner. The accessory
drawer is removable.
To insert the comparison standards, follow these steps:
• Remove the accessory drawer.
• Lift the holding clip for comparison standards, push the required standard
underneath and clamp it carefully.
Please observe the measuring direction shown by an arrow on the backside
of the comparison standards.
Align the comparison standard with this edge. It must not be positioned
behind or on top of the edge.

6 Measuring procedure
Choose two comparison standards
whose values are close to the expected
retroreflection of the marking to be
tested. Insert them into the device
aligned on the left and right edge as
described above.
Press the light switch (1) during the
whole visual testing procedure and
observe the road markings to be
tested and the comparison standards
through the observation window (5).
View through the observation window (3)
Compare the retroreflection of
the marking with the
retroreflection of the
comparison standards and
decide if the sample has a
higher or lower retroreflection.
Choose further comparison
standards and repeat the testing
in order to receive more precise
results.
In the example at hand, the retroreflection of the marking is higher than of both
comparison standards. In this case, two standards with values over 150 mcd . lx

, could be chosen, e.g. 175 mcd . lx-1 . m- and 00 mcd . lx-1 . m- , for a
second comparison to get preciser results.

7 Maintenance and cleaning
7.1 Maintenance which can be carried out by the user
Only the following maintenance and cleaning work can be carried out by the user:
• Outer cleaning of the device (see chapter 7. )
• Changing of the batteries (see chapter 7.3)
All other maintenance and repair work shall only be carried out by Zehntner
GmbH Testing Instruments or your authorized Zehntner agent, otherwise all
warranty is void.
7. Cleaning of the device
The ZVR 6000 does not need any special maintenance. The mirrors can be cleaned
with window cleaner and a soft cloth if needed.
For cleaning of the housing use a clean soft cloth. Use only soft cleaning agents.
Do not use strong acidic or alkaline liquids.
7.3 Changing of the batteries
After opening the battery case cover, the provided 4 AA batteries will be seen.
Empty batteries can be replaced either by commercially available new batteries or
by rechargeable batteries cell type AA. Remove the batteries from the battery
holder and insert the new ones according to the pole marking.
Never store the batteries inside the device if it will not be used for a longer
period or is exposed to direct sunlight for a longer time. Batteries have to be
recycled, respectively disposed separately from household garbage.
7.4 Comparison standards
Always handle the comparison standards with care and protect them from soiling
and scratches. They should be stored in the accessory drawer.
Never clean the comparison standards, as the values cannot be guaranteed
afterwards. In case of soiling they have to be replaced.
We recommend replacing the standards every years.

8 Graphical illustration of the measuring principles
8.1 Night visibility R L
R L is the coefficient of retroreflected luminance (night visibility) of road markings.
The observation angle of . 9° corresponds to the viewing distance of a vehicle
driver of 30 m under normal conditions. The illumination angle is 1. 4°.
The angle definitions above are valid for EN 1436. It is important to understand that
EN 1436 and ASTM E1710 use different illustration of the same angles.
