When Display Color is set to Color all thickness values between the Low Range
Thickness value and the High Range Thickness value are drawn using the color
yellow.
— Low Range Thickness
Sets the thickness value below which the B-scan is drawn using the color red
(Color scan only).
— High Range Thickness
Sets the thickness value above which the B-scan is drawn using the color
green (Color scan only).
• Encoder Resolution
Fixed property of the connected encoder, sets the number of encoder pulses per
unit of measure (encoded B-scan only).
• Scan Resolution (0.13 mm, 0.26 mm, 0.38 mm, 0.51 mm)[0.005 in., 0.010 in., 0.015
in., 0.020 in.]
Sets the interval of successive measurements (encoded B-scan only). The reading
resolution can be changed in the following increments:
— 0.13 mm (0.005 in.) — Takes a reading every 1 pulse
— 0.26 mm (0.010 in.) — Takes a reading every 2 pulses
— 0.38 mm (0.015 in.) — Takes a reading every 3 pulses
— 0.51 mm (0.020 in.) — Takes a reading every 4 pulses, and so on.
Scan resolution is limited to increments of the encoder resolution that you are
using. For example, if the encoder resolution is 7.87 pulses/mm (200 pulses/in.),
then the best resolution possible is 0.127 mm (0.005 in.). Each pulse from the
encoder is capable of taking readings in increments of 0.127 mm (0.005 in.).
• Start Coordinate
Sets the starting Distance Travelled (DT) position of the scan (encoded B-scan
only).
•Stop on LOS
Activates or deactivates the function to stop B-scan data acquisition when a Loss
of Signal (LOS) measurement occurs.
