Use and reading of the Roll Gauge (Disc Gauge)

The roll gauge is placed at the "0" (hole) at the beginning of the measuring section
and then unrolled to the desired end of the measurement .
Correspondingly all the turns count and add the remaining millimeters.

Example:

2 turns ( 1 turn / circumference 500 mm ) + the remaining millimeters e.g. 225 mm =
2 x 500 + 225 = 1225 mm total distance
