About Measuring
Measurement capability is optional on the XLG3 system. If your system has this option,
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.
The best LCD display setting for measuring is Unscaled. To learn about this setting, see
“Reviewing Settings for the System”
on page 42.
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 can be remeasured on a PC
using iView PC. For details, see
“Connecting to a PC or Network”
on page 34 (Step 4).
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
“Reviewing Settings for Image
Format and Quality”
on page 38.
