Setup Guide
Option B: using factory coefficients
Recommended to use factory default coefficient values if typical local dry road is not available and the
values cannot be copied from another sensor for which dry reference has already been done.
1. In the RoadAI app, scroll right in the measurement grid to check that the sensor uses the
following co-efficient values: 3.696, 3.729, and 3.664
If not, select Set Reference > Manual Road Reference, and type the 3 values.
Option C: copying coefficient values from another sensor
The sensor to which you are copying the values:
• Must have plate reference done
• Must be used in the same area as the sensor from which you copy the values
Recommended to copy dry road coefficient values from one sensor to another when dry road
reference has been done on a similar road surface before and surface coefficients are known.
1. Check the values from a sensor that you are using in the same area.
In the RoadAI app, scroll right in the measurement grid.
