Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.

GRX Online usage
GRX Online is an industrial sensor for continuously monitoring of retroreflective properties of sheeting ma-
terials at the production line. Retroreflective sheeting materials are used for traffic signs, high visibility
safety clothing, license plates and, conspicuity materials.
What does GRX Online measure?
GRX Online measures the value RA(coefficient of retroreflected luminance at night).
International measurement standards
The GRX Online measures the retroreflection and calculates RAaccording to international CEN and ASTM
standards. The instrument complies with the following European and US standards:
•EN 12899: Fixed, Vertical Road Traffic Signs, part 1-5
Part 1: Fixed Signs & Part 4: Factory Production Control
•EN 20471: High-Visibility Clothing - Test Methods and Requirements
•ASTM E 1709: Standard Test Method for Measurement of Retroreflective Signs Using a Portable
Retroreflectometer at a 0.2 degree Observation Angle
•ASTM E 2540: Standard Test Method for Measurement of Retroreflective Signs Using a Portable
Retroreflectometer at a 0.5 degree Observation Angle
•ASTM E 1809: Standard Test Method for Measurement of High-Visibility Retroreflective-Clothing at
a 0.2 degree Observation Angle and an Entrance Angle of -4 degree (discontinued).
RAis an important factor in the on-site quality control of road traffic signs.

Overview of GRX Online
The GRX online sensor measures Ra values for a given entrance angle for seven observation angles.
The GRX online sensor has a build in entrance angle of either -4 degrees (ASTM type) or 5 degrees (CEN
type). The observations angles are 0.2, 0.33, 0.5, 0.7, 1.0, 1.5 and 2.0 degrees. All observations angels are
measured simultaneously. The sensor measures all types and colors of retroreflective materials, when cali-
brated with one single white retroreflective standard with known RA. A calibrations standard can be sup-
plied as an option by DELTA.
Standard delivery
o1 pcs GRX Online Sensor.
o1 pcs Power-over-ethernet injector.
o1 pcs USB memory stick with PC control software and user guide.
Connecting the sensor
The online sensor is powered through the ethernet cable.
•Connect the sensor unit to the POE-injectors “OUT” socket*).
•Connect the POE-injector “IN” socket to the PC*).
•Connect the POE-injector power cable to an electrical outlet.
*) Ethernet cables must be CAT5 or better.

When the sensor is powered correct the green LED on the rear cover plate will be flashing slowly (1 Hz).
Mounting the sensor in the production line
Mount the sensor so the black end cover (with the measurement window) is parallel to the sheeting and
with approximately 100 mm. The illumination angle (-4° or +5 degrees) is determined by the internal optics.
See the section Mechanical drawing

Software installation
Double-click the “setup” file (eg. on the enclosed USB stick). When the install window shows up click “In-
stall”
After a few seconds the program is installed, and the program starts up:
Program location:
The program is installed in the default Windows program location:
C:\Users\<Your user name>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\DELTA
Furthermore, a short cut is placed on the Windows desktop.
Connecting to the sensor to the PC
General
The sensor communicates over ethernet. The computer running the control software must be configured to
access the sensor.
The sensor is configured with a fixed IP address on the private subnet 10.201.201.0.
Sensor IP address (fixed): 10.201.201.5
The control computer should be configured with a fixed IP address on the same subnet.
The proposed network configuration is this:
Fixed IP address: 10.201.201.2
Netmask: 255.255.255.0
Note:
If the ethernet port on the pc is used for other purpose you can purchase an “USB to ethernet adaptor”
to get an ethernet port

Configuring the network adapter
Open the Control Panel and start “Network and Sharing center”, then select “Change adapter settings” and
then select “Properties”
Select “Internet Protocol Version 4 (TCP/IPv4)” and click “Properties”
Select “Use the following IP address:”
Enter IP address: 10.201.201.2
Enter subnet mask: 255.255.255.0
Click “OK” and “Close”

Calibration procedure
The sensor does not compensate for the distance to the sheeting. Therefore, it is necessary to perform the
calibration with the calibration target in the actual measuring distance.
Place the calibration target in the same distance as the sheeting.
Start streaming to help position the calibration target. The illuminated circle should be in the center of the
calibration target.
Stop streaming when the target is positioned correctly.
Click “Calibrate” and enter the calibration values for each observation angle.
Enter the calibration values in the calibration window:
Click “Calibrate” to perform the calibration. Click “OK” to close the confirmation window.

GRX Online Retroreflectivity Sensor User Manual 12 DELTA a part of FORCE Technology
May 2018
Start streaming while the calibration target is still in place to verify that the measured data matches the val-
ues entered.
Start/stop measuring
Stream: Measurement period must be at least 200 milliseconds. The actual measuring time is approxi-
mately 50 milliseconds shorter.
In general, the lower measuring times result in lower precision, i.e. greater variations in the measurement
results.
When the sensor is measuring the green LED on the rear cover plate will be flashing quickly (10 Hz).
The measurement grid scrolls automatically when a measurement is received. The grid can hold a maxi-
mum of 50.000 measurements. When the limit is reached, the oldest measurements are removed from the
grid.
Start/stop logging
Select “Start log” to start logging measurements to a file.
The current logfile is shown in the status bar:
If a file with the same name already exists, the measurement data will be appended.
