Image-Sizing Cursors (Phased Array Mode) 271
16. Image-Sizing Cursors (Phased Array Mode)
This chapter describes the sizing cursor features on the EPOCH 1000 Series. The
topics covered are as follows:
• Cursors X and Y
• Cursors Status
• Cursor Positioning
• Cursor Measurements
16.1 Cursors X and Y
The EPOCH 1000 Series provides two sets of sizing cursors in phased array mode.
These cursor sets are only available when freeze is active on the instrument.
These two cursor sets are applied to the S-scan image to allow visual reference and
sizing of image components. The X cursor set (X2, X1) allows measurements in the
horizontal plane, and the Y cursor set (Y2, Y1) allows measurements in the vertical
plane. Because the S-scan image provides scaled representations of defects, these
cursor sets can provide accurate flaw sizing such as cracks and delamination.
16.2 Cursors Status
To activate the image-sizing cursors
1. Press [FREEZE] to activate freeze.
2. Select 1/5 > PA Cursors > Cursor X = On or Cursor Y = On.
