roads and on moistened road markings (e.g. according to the “bucket” method)
•
Set a timer (e.g. stopwatch) depending on the standards
•
Moisten the road marking in the required
way, e.g. with the “bucket” method.
The ZRM 6006 should be far enough away that it will not get wet.

Wait until approx. 10 seconds before the timer setting expires and set the
instrument onto the previously moistened road marking.
•
Start the measurement when the timer reached zero.
Never pour water on the instrument.
