TACHOGRAPH CHART.

TM 9-2320-211-20-3-2

a. Description.

The chart is made of a strong red backing paper covered on both sides with a

thin wax coating. Each tachograph stylus cuts a groove in the wax coating so the red

backing paper shows. The red lines that show are the tachograph recordings.

The chart (fig. 20- 1) is divided into four recording fields by green and blue

markings so that the red lines that the stylus makes can be read. The recording

field printed on the front side is green; the field printed on the back side is blue.
