Paper Feed and Writing Mechanisms
The majority of analog recorders utilize either strip charts or circular charts. The strip charts, supplied in rolls, have the great advantage that they can operate continuously for long periods without need of replacement. Circular charts, on the other hand, must be replaced periodically, and hence are used mostly for recording slowly changing variables, a single chart to last, perhaps, one day or one week (Figure 6-1).
