INSTRUCTION MANUAL FOR SLED-BORNE TIMER.
Abstract
A portable time code generator which approaches laboratory stability in a rugged unit designed for sled-borne operation is described. In operation the Model CGT-150 timer is mounted on the sled and connected to a block house control unit via hard wire. A manual switch on the block house control unit permits the operator to disconnect the sync signals prior to sled pull-away to check for drift in the sled-borne timer. The drift may be monitored on a visual display mounted in the block house control unit which indicates the phase difference in micro-seconds between the master and the sled timers. This permits a convenient last minute check of the system prior to sled firing. As an additional check on the system, a pulse by pulse comparison is made between the master and sled timers. If the sled-borne timer drifts out of sync with the master, a red light and buzzer sounds the alarm. A voltmeter on the front of the block house control unit monitors the battery voltage supply for the sled-borne timer. (Author)
