14.4.3 Practical sample of interval timer
The interval timer can be used e.g. to define the performance of the retroreflection of a marking
in dependence on the effluent water at wet measurements. At the interval timer the first
measurement starts right after pressing the measuring button
. It is recommended to
combine the interval timer with the wet timer if the first measurement should start after a certain
period after the measuring button has been pressed. Please also refer to chapter 14.4.4
„Practical sample combination of wet timer and interval timer” on page 53.
Here, the performance of the R
L
-value of a moistened type-II road marking tape is measured
during 60 seconds at an interval of 5 seconds. As the measurements should start right after
moistening the road marking tape, it does not make sense using the wet timer. This example
requires the following settings:
The interval timer has been activated as mentioned in chapter 14.4
The interval time has been set at 5 seconds as described in chapter 14.4.2
Interval counts: 12
The interval counts has been set at 12 as described in chapter 14.4.2
page 49.
After carrying out the measurements we exported the measuring data to Microsoft Excel using
the software „MappingTools“. For doing so the measuring data needed to be stored before on
an USB flash drive as described in chapter 12.6
„Storing the measuring data on a USB flash
” on page 42 or you get direct access to the
described in chapter 13
„Data export and MappingTools software” on page 43.
