If the Start Sentinel character on a card is not found by the Tester, an indication as shown in
Figure 3-7 will appear on the screen. Although the Start Sentinel Location graph, shown in
Section 4, may indicate a position of the start sentinel, the value in the graph is the distance
calculated to the first “1” bit on the card and not the Start Sentinel character.
