About Measuring
Measurement capability is a standard feature on the XLG3 system. You can measure
features or defects either before or after saving an image (if the image was saved in
measurement mode). You can save up to five measurements per image. In order to
perform 3D phase, stereo or shadow measurements, the image must be captured using a
3D phase, stereo or shadow tip.
Measurement results are valid only for measurements taken in air. For measurements
taken in liquid, contact GE Inspection Technologies.
GE Inspection Technologies cannot guarantee the accuracy of measurements calculated
by the XLG3 system. Accuracy varies with the operator's ability.
All measurement images saved using the XLG3 system, except for 3D phase images, can
be remeasured on a PC using remeasurement software from GE's Inspection
Technologies business. For details, see
Network"
The XLG3 system can display measurement images that were captured on the Everest
XL PRO™ VideoProbe system, including their previously captured measurements.
However, you cannot remeasure these images on the XLG3 system.
About Measurement File Formats
You can save measurement images as JPEGs or bitmaps. You can view these files,
including the measurement results, in most .BMP or .JPG viewing applications, such as
Windows Paint. To learn how to change the file format, see
