Superimposed recordings.

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

(5) Superimposed recordings.

(a) Problem. Distance and speed recordings show the truck was

stopped and moving at the same time.

(b) Cause:

1. The tachograph was opened and the chart was turned back so

long stops were not recorded (Fig. 20-22, detail A).

2. The chart was in the tachograph more than 24 hours and the

recordings of one day were made on top of the other recordings (Fig. 20-22, detail

B). Check time the chart was put into the tachograph.

3. Recordings have been made by hand (Fig. 20-22, detail C).

These recordings will not look like the recordings made by the tachograph.
