MX2 Training Program - Displaying Data Overview The MX2 data view area displays the various ultrasonic data views with

preconfigured layouts.

A data view is a 2D graphical representation of the ultrasonic data with a ruler orscale corresponding to the horizontal and vertical axis.

Data views available in the MX2 are: Ascan. !ltrasound axis vs. a"plitude axis.

#scan. !ltrasound axis vs. scan axis.

$scan. !ltrasound axis vs. index axis.

%scan &' degree or linear angle( )ndex axis

vs. scan axis.

%scan &$scan( *ocal law vs. scan axis.

$trip charts.

+ay tracing.

A layout is a preconfigured window with

one or "ore data views. ,ictured to the left is the A$-% layout

pictured with "ultigroup &$/ew 0' and

21'( configuration typical of the %obra

s"all dia"eter piping inspection.

The Ascan is the source fro" which all other views are created.

The Ascan data view is the 2D wavefor" representation of the receivedultrasonic pulse a"plitude vs. ti"e of flight.

The MX2 uses an 8 bit &'9'' a"plitude( resolution for the digitized A

scan and 9' bit &'2'' a"plitude( for the gate readings and %scan.

A"plitude axis resolution between '9'' is '.; &2 9''

The higher the point @uantity the better the resolution on the Ascan.

The point @uantity is a co"pro"ise between file size and Ascan resolution. 2'=;' points is sufficient for the "ost co""on inspections and ensures

precision readings.

MX2 Training Program - Displaying Data - S-scan The MX2 $scan is a 2D end view of ultrasound data presenting all Ascans within

the group in an angular sector or sweep range creating a cross section of the

inspection.

The Ascans are converted to color coded lines representing a"plitude and are

corrected for delay and true depth relative to the ultrasonic axis.

The MX2 #scan data view represents the ultrasonic data with a proEection of the

scan axis and the ultrasound axis for one focal law or Ascan only. The vertical ultrasound axis is generated fro" the co"plete Ascan range &Fot gate

range( and the horizontal scan axis is generated fro" the "ove"ent of the probe.

The #scan is an uncorrected data view that allows the s/ip lines '7 T97 etc( and

gate position to be displayed on the data.

The T5*D #scan is explained in detail in the T5*D special applications section.

both a"plitude and position %

scans are available.

The %scan gate data can be

saved independently with or

without the digitized Ascan.$aving only the %scan data

results in faster ac@uisition speed

and s"aller data file size.

*ile saving options are covered in

the inspection preparation section.

The type of %scan available for the group depends on the type of focal law

configuration that was selected during the group and focal law wizard or in the

*ocal 3aw%onfiguration3aw%onfig para"eter. There are options:9. $ectorial Angular $ector &MX2 default $scan(

2. 3inear $ector &Cscan at angle(

. 3inear at ' degrees &Cscan at ' degrees(

The %scan is generated based on the gate position and gate "ode. %scans can

be configured for gate A and gate # independently.

The ray tracing data view is a 2Drepresentation of the wedge and weld

The bea" path for the current focallaw will display a colored circle at the

volu"etric position of the "axi"u"a"plitude signal in gate A.

The ray tracing is pri"arily areporting tool and is dependent onthe operator selecting the correct Ascan and gate position for the

displayed flaw. The nu"ber of selected legs will li"it

the display based on part thic/ness. The ray tracing tool is covered in

detail in the indication table andreporting section.
