VII. MEASUREMENT
Once the radar has been installed and configured, the software allows you to switch to
"measurement" mode and the software displays the data related to the measured vehicles as they
pass:

For the direction of movement in bidirectional mode, the " - " indicates movement away (the lane
closest to the radar), the " + " indicates movement towards the radar.
Check that the lengths are correct. A private car should be measured between 3 and 5.5 m, a truck
should be longer than 6 m. Some differences can appear, mainly due to the slope of the road and/or
the fact that the installation mast is not vertical. It is possible to adjust the inclination of the antenna
to the installation conditions by clicking on “Modify radar parameters”.
Note
In order to verify the accuracy of the length measurement, we recommend you to carry out the
configuration and commissioning on site with a laptop computer or a smartphone. However, if you do
not have the required equipment, the configuration can always be done in advance. The commissioning
then consists solely of pressing the power pushbutton. The radar will switch to measurement mode
automatically after approximately five minutes. The counting can be checked using the indicator lamp.
Verification of the accuracy of the speed and length measurements can only be done with a laptop
computer or an Android smartphone with the TMS-SA App installed.
