ABSTRACT:
In a potentiometric chart recorder, the speed of the chart motor 22 is, in one mode of operation (AUTO) selected by a switch 32, varied between two values in dependence upon the rate of change or slope of the input signal at 10 as detected in a detector 30. The slow speed is obtained by intermittent operation at the fast speed, and during the non-operative periods power-consuming circuitry e.g. 16, 18, 26 is switched off by a switch 40.
