Abstract :
A new type of strip-chart recorder is described that has been used extensively on high-altitude balloon flights. Driven by a stepper motor and powered by a wide-range timing circuit, it maintains an accurate timne base. The unit is particularly suited to applications where severe environmental conditions are encountered and low battery drain operation is necessary.
