piece. When set to

Note:
Based on the values input for the
PROBE ANGLE
,
THICKNESS
,
X VALUE
, and
O DIAMETER
parameters, the instrument
operates in one of five modes. Each of these modes is represented by an icon in the icon area at the upper left corner of the screen.
See Figure 6 on page 17 for an illustration of these icons.
