Tracking Validation
The tracking must be visually controlled and validated. If the
tracking results are visually correct press the red Approve
button. The button turns green and is labeled Approved. The
calculated values will be stored and later appear in the
worksheet.
If tracking needs correction there are several options:
• If required, press Layout softkey to enlarge the ES and ED
frames and position them side-by-side (Figure 7-29).
• You may manually select a different ED frame or ES frame
using the ED frame or ES frame softkeys.
• You may edit any misaligned point on either ED or ES
