Defining the Scan – LINEARThe sequence in which the phased array probe’s elements fire are defined 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 firing 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)

1212 13

Defining the Scan - SECTORThe sequence and pattern at which the phased array probe’s ele-ments fire are defined 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 definition)

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.

1616 17

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 DelayPress • to set the Gain Increment Value -- The amount of gain change with each click of the Gain Knob. Options include a user-defined gain step and a gain knob LOCK. Press and hold to switch between analog and digital gain.

1818

Viewing Measured Results To determine which measured results are displayed, press to access the DISPLAY menu

Set Readings in Each of the Four Small Boxes – • RESULTS1Set Readings in the Large Box – • RESULTS2

CHOICES INCLUDE:BEAM— Angular position of the Beam CursorP%A/B— Peak amp. of all beams in scan currently captured by Gate A or B(as a % of FSH)PSA/B— Soundpath distance of peak beams in scan currently captured by Gate A or BPPA/B— Projection distance of all beams in scan currently captured by Gate A or B

1818 19

PDA/B— Material depth of all beams in scan currently captured by Gate A or B.PZA/B— Minimum material depth (incorrected according to material thickness) of all beams in scan currently captured by Gate A or BA%A/B— Amplitude (as a % of full-screen height) of the highest echo to cross A-Gate or B-Gate in the beam selected by the beam cursor.SA/SB— Sound-Path distance or duration represented by the highest echo to cross a Gate in the beam selected by the cursor.SBA— Useful for calibration of the material velocity.PA/PB Projection distance according to the origin (front of the wedge if “Probe/Origin Offset”= 0 from the probe’s index

Freezing the Display The displayed image and measured values can be frozen by pressing

. The freeze menu appears across the bottom of the display. Use these features to manipulate or evaluate the frozen image.

CURSOR 1—Operate a horizontal cursor with the Gain Knob and a Vertical or Beam Cursor with the Function Knob. It also allows the user to display an ORIGIN LINE corresponding to the WEDGE FRONT plus ORIGIN OFFSET (if any) distances to represent the user-definedtarget location.CURSOR 2—Operate a second (color coded) horizontal cursor with the Gain Knob and a Vertical or Beam Cursor with the Function Knob. This menu also allows the user to display an ORIGIN LINE corresponding to the WEDGE FRONT plus ORIGIN OFFSET (if any)

2424

MEAS 1—Select up to four READING options that correspond to the point defined by the intersection of CURSOR 1’s horizontal and vertical components. MEAS 2—Select up to four READING options that correspond to the intersecting point defined by the intersection of CURSOR 2’s horizontal and vertical components.RESULTS1—Display the four READINGS that were operational prior to freezing the display.OFFLN DB—Change the Gain that’s applied to the frozen display.FILENAME—Launch the data set naming (or report generating) process.

Working with Data Sets Instrument settings and report contents can be stored in a data set file. When recalled, instrument settings are automatically returned to those found in the stored data set. Access the data set related functions by pressing to activate the FILES menu. A new Data Set is created as follows:

Press • next to ACTION until STORE DATASET appears.Press • twice next to FILENAME. Use the two knobs and the instrument’s text-entry feature to input the new data set’s name.Press • next to SOURCE/DEST until the desired file-saving desti-nation appears.INT MEMORY – A limited number of data sets can be stored in the • instrument

2626

SD CARD – Primary destination for data sets • DIALOG PROBE – Abbreviated data sets can be stored in dialog • probesWith the desired data set name input, press • next to ENTER to complete the data set creation process.An existing Data Set is recalled, as follows:• Press • next to ACTION until RECALL DATASET appears.Press • next to SOURCE/DEST until the file’s current location appears.Press • next to FILENAME. Turn the Function Knob until the desired data set is listed.Press • next to ENTER to recall the data set, automatically setting the instrument’s parameters to the stored configuration.

2626 27

Working with Data Sets Instrument settings and report contents can be stored in a data set file. Stored data sets can be deleted or edited. Access the data set related functions by pressing to activate the FILES menu. An existing Data Set is deleted as follows (refer to Card 2 for help in making adjustments):

Press • next to ACTION until CLEAR DATASET appears.Press • next to SOURCE/DEST until the file’s current location appears.Press • next to FILENAME. Turn the Function Knob until the desired data set is listed.Press • next to ENTER to delete the data set, press when indicated to confirm the deletion. Data sets can not be recovered.

2828

An existing and active Data Set is edited, as follows:With the data set active, change instrument settings as desired.

Press • next to ACTION until STORE DATASET appears.Press • next to SOURCE/DEST until the current data set’s storage location appears.Make no changes to the name of the active data set. Press • next to ENTER to complete the data set saving process. The existing data set will be overwritten with the modified version.

Generating ReportsReports can be generated and stored on the instrument’s SD card. These reports can contain various user-selected components includ-ing instrument settings, displayed image, report header, and memo. Reports are generated in much the same way as a data set file (refer to Card 2 for help in making adjustments):

Press • to access the FILES menu.Press • below HEADER, MEMO, or REPORT to determine the report’s contents. Press next to EDIT, then turn the knobs to input header or memo text. Make the following settings:

HDR IN REPORT – Set to YES to include a header MEMO IN REPORT – Set to YES to include a five-line memoPARMS IN REPORT – Set to YES to include a listing of settings

3030

IMAGE IN REPORT – Set to YES to include display imagePress • next to ACTION until STORE REPORT appears.Press • twice next to FILENAME. Use the two knobs and the instrument’s text-entry feature to input the new report’s name.Press • next to SOURCE/DEST until the SD CARD destination ap-pears. Reports can only be stored on SD cards. With the desired data set name input, press • next to ENTER to complete the data set creation process. The SD card display icon will flash. Pressing and holding • for three seconds will automatically store a report.
