Conguring for a Probe and Wedge
Access the probe and wedge settings by pressing to activate the
PROBE menu. Wedge features are adjusted as follows:
Wedge Offset Z – • PROBE then WDGE GEO (user measured
from Probe Index Point to contact surface – set to 0 when no
wedge is installed)
Wedge Angle – • PROBE then WDGE GEO ( user measured
wedge angle – set to 0 when no wedge is installed)
Wedge Front – • PROBE then WDGE GEO (user measured
from Probe Index Point to wedge’s front edge – required to use
the origin offset feature)
Origin Offset – • PROBE then OFFSET (user measured from
wedge’s front edge to the target)

Markings on the probe body indicate the location of element 1 and the
direction that additional elements are arranged. To dene the
orientation of the probe’s elements with respect to the wedge’s
geometry, access PROBE menu then WDGE DAT submenu.

Dening the Scan – LINEAR
The sequence in which the phased array probe’s elements re are
dened using features located in the SCAN menu.
For LINEAR scan types set the following:
SCAN TYPE – • ELECTRNC (choose linear)
WAVE TYPE – • ELECTRNC (shear or longitudinal)
ANGLE START – • SCAN PATT (constant ring angle for linear)
First Element – • APERATURE (element where it begins)
Number of Steps – • APERATURE (number of steps in scan)
APRERATURE SIZE – • (number of elements in the step)
APRERATURE STEP – • (number of elements stepped from one
step to the next in the linear scan)
CALC – • SCAN PATT (calculate delay laws)

Dening the Scan - SECTOR
The sequence and pattern at which the phased array probe’s ele-
ments re are dened using features located in the SCAN menu. For
SECTOR scan types set the following:
SCAN TYPE – • ELECTRNC (choose sector)
WAVE TYPE – • ELECTRNC (shear or longitudinal)
ANGLE START – • SCAN PATT (starting angle for sector scan)
ANGLE STOP – • SCAN PATT (stopping angle for sector scan)
ANGLE STEP – • SCAN PATT (angular increment between steps)
First Element – • APERATURE (element where it begins)
APRERATURE SIZE – • (number of elements in the step)
CALC – • SCAN PATT (calculate delay laws – required with
changes in scan denition)

Pulser and Receiver Setup
Access the UT menu to set the Pulser and Receiver operation •
Pulser Voltage – PULSER
Pulser Width (in nanoseconds) – • PULSER
[(1/probe frequency) /2]
Receiver Frequency – • RECEIVER (includes lter settings)
Rectication – • RECEIVER (includes halfwave, fullwave, and RF)

Gate Position and Operating Modes
The instrument has two gates (A and B) which are congured by rst
pressing to access the UT menu:
Select Gate to be Positioned – • GATE POS
Gate Starting Point – • GATE POS
Gate Width – • GATE POS
Gate Threshold – • GATE POS
Time of Flight Calculation – • GATEMODE (TOF MODE to Peak or
Flank)
Gate Triggering Logic – • GATEMODE (A gate with positive logic
triggers when crossed, negative logic triggers when not crossed,
and also allows gate to be disabled)
Display or Hide Active Gate – • GATEMODE

Viewing Scans
With the phased array probe coupled to a test piece, there are various
ways to view the resulting scans and measured data.
Press to choose between A-Scan, Sector (or Linear) Scan, or both A
and Sector (or Linear Scan).
Press to access the DISPLAY menu and determine the measured
results displayed as follows :
Link the A and Sector (or Linear) Scans Vertical Size – • VIEW
then set ASCAN MODE to BUD (Beam Ultrasonic Depth)
Display Leg Lines – • DISPLAY then BACKGRND, COLOR LEG on.
Control the On-Screen Beam Cursor - press • two times then
Right Knob.

Press• the LEG to change the number of displayed Legs (which
represent each pass of the ultrasound through the test piece).
Press• , UT, BASE, DISPLAY DELAY to adjust the Display Delay
Press• to set the Gain Increment Value -- The amount of gain
change with each click of the Gain Knob. Options include a user-
dened gain step and a gain knob LOCK. Press and hold to
switch between analog and digital gain.
