ABSTRACT:
A tachograph includes stylus recorder (4,5,6) responsive to a signal related to engine speed for recording an indication of the engine speed on a chart (1). The stylus recorder is conditioned to provide a bar trace having different and readily distinguishable levels. Each level represents a threshold of engine speed which indicates that the engine speed is at or below the respective threshold and within a predetermined range. Threshold selector (8 or 9) are provided for adjusting the relationship between the levels and the predetermined thresholds so that the bar trace levels stay substantially the same but represent engine speed thresholds which are adjustably predetermined by the threshold selector.
