EXTERNAL CONNECTOR IDENTIFIER

The external connector identifier is a large circle which contains the paragraph number of the trouble-

shooting chart and a specific item on that chart, or the number of the next chart in the performance

test sequence. Therefore, a large circle always references some information external to the flow chart

containing the circle.

NOTE

An external connector identifier always completes the performance test chain.

NOTES

The third column on each performance test chart sheet may contain notes to clarify information

contained in the chart.
