“Sel. Reflector” (selected reflector):
Display of set up reflector
“Rating”: The calculated reflector format provides a check of the
conformity between measured reflector and set antipole.
“Condition”: With the calculated coefficient, it is possible to
assess whether a reflector is damaged (but still measurable) or
destroyed (not measurable).

Functionality check acc. to TP D-StB 12
“
Before starting the day’s first measurement, the thickness measuring
device’s functionality must be tested.”

The German standard TP D-StB 12 requires that the first measurement
has to be a check of the correct device function. For this, with the
device traverse the measuring site and perform a measurement. Use
the MIT wheeled spacer (s. Fig. 33) and fix it to the probe. Repeat the
measurement with a mobile spacer. The MIT wheeled spacer increases
the distance between probe and road surface by 35 mm.
