The timer is composed of two units the timer proper and a control unit. The timer proper with self-contained batteries is housed in a 3 in. x 3 in. x 7 in. aluminum enclosure. It needs only a styrofoam outer insulation barrier and may be mounted anywhere on the balloon flight train. A pigtail connector from the timer proper must be mated to the timer control unit. This allows the operator to preset the desired time delays. The timer control unit also contains the time display and a switchable fast self check feature.
