8.4 Information for a proper measuring procedure
For most accurate measurements the device should be placed as planarly as
possible. If there is significant unevenness in the road marking use the positioning
support.
8.5 Measuring profiled markings
The Zehntner ZRM 6010 is capable of measuring profiled road markings with
profiles of heights between -1mm up to +15 mm.
The measuring geometry is according to the standards EN 1436 and ASTM E1710
within this range. Profiles with heights out of this range can evoke wrong measuring
results. This fact depends also on the gap between the single profiles (refer to
Chapter 8.5.3
„Comments to the measurement of profiled road marks“ page 30).
It is recommended to use the enclosed positioning support to obtain most accurate
measurement results.
8.5.1 Preparation
Mounting the positioning support is quick and easy. Lay the positioning support to
the floor, tilt the instrument slightly to the front and slide it in this position into the
frontal prong support. Tilt the device back into horizontal position, it should click into
place.
Ensure proper fixation by raising the instrument shortly.
