3 Delivery of device
3.1 Damages during carriage
On the receipt of the goods, check for any visible damages on the packaging. If it is
undamaged you may sign the receipt of the goods. If you do suspect by your visual
inspection that damage has occurred, make a note of the visible damage on the
delivery receipt and request the courier 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 liable immediately 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 carrier, which is normally 7 days. However, the period could
vary depending on the courier. Hence, it is recommended to check the exact time
limit when receiving the goods.
If there are any damages also inform your authorized Proceq agent or Proceq SA
immediately.
3.2 Shipment
Should the device be transported again, it must be packaged properly. Preferably
use the original packaging for later shipments. Additionally use filling material in the
package to protect the device from any shock during carriage.

9
3.3 Standard delivery
Following parts are included in the delivery:
1 ZRM 6006 Retroreflectometer
1 calibration standard
1 universal battery charger
(100-240V, 50-60 Hz)
1 certificate of manufacturer
1 certificate of calibration
1 carrying case with wheels

10
3.4 Carrying case
The ZRM 6006 is delivered in a transportation case. Whenever you want to
transport the instrument, use the case. Nevertheless, please take care that for
shipments the case has to be put into a cardboard box and protected with filling
material. The transportation case is an optimal storage case for the equipment.
When not in use, The ZRM 6006 should be locked into the calibration standard and
safely stowed in the carrying case.

5 Setting up
With a short press of the on/off button the device is switched on or off.
You will see the Zehntner-logo and the firmware version during switching on before
the display changes into measuring mode.
For switching off the instrument you have to press the on/off button .
6 Calibrate
6.1 Calibrate
To ensure precise and valid results the ZRM 6006 must be calibrated by the user
on the working standard in regular intervals (recommended interval: every 2 days).
Put the ZRM 6006 on the working standard, switch it on and press the measuring
button longer than 5 seconds until the calibration values are shown on the display.
Release the measuring button. The instrument is in calibration mode now. To
execute a calibration, press the measuring button shortly.
If the measuring button is not pressed within 2 seconds,
the instrument switches back to measuring mode and
the main screen will be displayed.
If the calibration is successful, a check will be shown
behind the calibration value. If the calibration value differs from the factory
calibration by more than 15% an X will be displayed.
Values with high deviation will not be accepted
automatically. If the text “PRESS M TO ACCEPT ANY”
is displayed and the measuring button is pressed the
calibration out of range can be accepted.
If an error occurred during calibration, “-“ will be
displayed behind the calibration value. In this case it is
not possible to accept the calibration value. Please
contact Proceq SA or your authorized Proceq-agent.
For calibration the device must be positioned
exactly on the standard. Make sure that the snap-lock mechanism of the
standard is attached correctly to the instrument.

13
6.2 Calibration standard
Always protect the calibration standard from dust, moisture and other environmental
factors. It is recommended to keep it stored in the ZRM 6006 case. The standard
values measured in the factory as well as the serial number of the corresponding
instrument can be found on the sticker on the inside of the standard.
It is valid for 2 years and should be replaced or recalibrated by Zehntner after this
time.
The working standard delivered with the ZRM 6006 is not changeable and is
valid only for the delivered instrument.
6.3 Cleaning of the calibration standard
If the calibration standard is soiled or covered by dust, it can be cleaned carefully
using window cleaner and a soft tissue.
A damaged or a polluted calibration standard may cause incorrect calibration
and therefore incorrect measuring results.

7 Measure
After switching on the ZRM 6006 a splash screen is
displayed, which shows the firmware version.
After about 2 seconds the instrument switches to the
main screen, displaying the measured values, the
temperature and the relative humidity. Additionally the
battery and charger status and eventual warnings (BAT
LO, BAT CRIT) are displayed.
To make a measurement press the measuring button
shortly (not more than 4 seconds).
7.1 Carrying out exact measurements
The ZRM 6006 should be placed as even as possible. Put the ZRM 6006 on the
sample or marking to be measured. For unevenness from -1 mm up to 5 mm in
longitudinal direction, the given measuring geometry is warranted. Bigger
unevenness may lead to wrong measuring results. Please observe in such cases
the chapter 7.2 “Measuring profiled markings from 5-12 mm” as from page 16.

15

16
Ensure that the marking you want to measure is as flat as possible along in the
whole range of the measuring instrument. Otherwise, the measuring geometry
would be adulterated. Crooked or twisted samples will cause incorrect measuring
results. For unevenness from -1 mm up to 5 mm, the given measuring geometry is
warranted
The procedure for measurement in the laboratory is the same. Observe likewise
that the samples are absolutely flat. The length of the samples should be at least
500 mm in order to guarantee that the instrument stands on all 3 feet.
Make sure to use large enough, absolutely plane samples, insensitive to
moisture, as e.g. sheet steel.
7.2 Measuring profiled markings from 5-12 mm
The ZRM 6006 is capable of measuring profiled road markings with profiles up to 5
mm. However, if the profile is higher than 5 mm you will need to follow a certain
procedure in order to get reasonable values.
If the distance between the profiles is more than 300 mm, a support plate is needed
with the same height as the profile to ensure the correct measuring geometries.

17
7.2.1 Getting started
The procedure is shown on the ZRM 6013. The shown procedure is identical
for the devices ZRM 6006, ZRM 6013 and ZRM 6013+.
Locate the two indicators on the Retroreflectometer “measuring area” and
“measuring direction”. Point A is at the end of the arrow: “measuring direction”,
Point B is at the end line of the “measuring area”. These indicators are located on
both sides of the equipment.
When measuring a profiled road marking, the raised part of the road marking has to
be located between point A and point B.

18
7.2.2 Measurements with profile distances under 300 mm
1. Place the instrument on the profile whereas Point B is on the middle of the
profiled marking, take a measurement.
Chosen profile
2. Move the instrument forward for approximately 5 cm and take the next
measurement.
Chosen profile

19
3. Move the instrument forward once again, so that Point A is in the middle of
the profiled marking and take a measurement.
Chosen profile
4. Make the average value of the three measurements. Repeating this
procedure on further measuring points ensures a better accuracy.

20
7.2.3 Measurements with profile distances over 300 mm
If the distance between two profiles of the marking is more than 300 mm, a support
plate is needed to make sure the device sits even on the marking. The support plate
has to have the same height as the profile of the marking to be measured.
The support plate has always to be placed at the rear
side of the instrument and can reach maximum to the screws of the base plate. To
all other side unlimited.
Correct placement of the support plate:
Screws of the base plate
1. Place the instrument on the profile whereas Point B is on the middle of the
profiled marking, take a measurement.
