Negative measurements indicate

Positive measurements indicate

Cursor Placement:
Place the first three cursors to
define a reference plane. Place the
fourth cursor at the perpendicular
distance you want to measure.
Note: Depth measurements
taken at a low accuracy index
are particularly sensitive to the
matching cursor's position. If the
accuracy index is low, increase it
by bringing the probe tip closer. If
you cannot increase the accuracy
index, place cursors so that they
yield high match strengths, and
verify your accuracy.
