    Setup Instructions for the MX2

    Firstly connect the probe to the OmniScan. If making a double sided setup connect probes to splitter and then connect splitter to the OmniScan.

    FILE > NEW

    WIZARD > PART+WELD (Follow through wizard)

    Enter THICKNESS

    WELD TYPE = V OFFSET

    Enter weld configuration

    FINISH

    WIZARD > SETUP (Follow through wizard)

    MODIFY SETUP > NEXT

    PROBE = If not auto recognised choose probe

    WEDGE = Add wedge

    NEXT

    LAW CONFIG = SECTORIAL OR COMPUND (this will be in scan plan)

    First Element = Scan Plan

    NEXT

    ANGLES = Enter MIN and MAX angles and ANGLE STEP (scan plan)

    NEXT

    INDEX OFFSET = Scan Plan

    FOCUS DEPTH = Either 1.2 thickness or for thickness above 25mm, root 1 setup and cap 1 or Scan Plan

    GENERATE

    UT SETTINGS > GENERAL

    RANGE = Change to 6 or 7 skips for calibration purposes.

    PULSER > ENERGY = Scan Plan/Technique sheet

    RECIEVER > FILTER = Change to bandpass filter to suit probe frequency (10MHz = 10MHz Bandpass)

    WIZARD > CALIBRATION

    MODE = SENSITIVITY

    START > NEXT > NEXT

    Put the probe on the block and scan a hole between ½ T & T.

    Adjust gates to start just before selected hole and just after. It helps to set gate thresh hold low (between 0 & 5%)

    Move probe back and forward so the hole signal goes across the S-Scan and the green line will begin to appear. If it isn’t showing across the whole range, then add dB. Once the green line is maximized hit CALIBRATE.

    Now move probe back and forward to get the green line to 80%. If it is to low or to high in places press CALIBRATE again. When it is good >

    ACCEPT

    FILE > SETUP > SAVE

    Now take out 5 or 6 dB on the main gain setting

    WIZARD > CALIBRATION

    MODE=WEDGE DELAY

    Select a hole between 1/2T & 2T

    NEXT

    DEPTH=Depth to centre of hole (look at drawing)

    TOLERENCE=0.1

    NEXT > NEXT

    Set the gate to just before and just after the hole you have chosen.

    THRESHOLD=20%

    Get hole signal around 80% and move probe back and forward to get the white line across the screen.

    CALIBRATE

    Now check calibration by moving probe back and forward again. (you may have to change the gate now that the wedge delay has changed)

    If calibration is bad, then repeat these steps.

    If calibration is good, then ACCEPT.

    WIZARD > CLAIBRATION > TYPE =SIZING

    MODE=TCG

    START > NEXT > NEXT > NEXT

    Adjust range so hole can be picked up across all angles.

    NEXT

    Adjust gate over 1st hole

    NEXT

    Reduce dB so green line is around 50% and move probe back and forward to complete green line across the screen.

    ADD POINT – now check the green line sits at 80% by moving probe back and forward. If bad CANCEL POINT and start that hole again.

    If good, NEXT POINT

    Repeat these steps for all TCG holes. Minimum of 3 within the test range.

    When all holes complete ACCEPT TCG

    UT SETTINGS > RANGE

    Adjust range to cover inspection area

    GATES

    Adjust gates to start above root area and below full skip / 2T

    SAVE SETUP

    Hello, I would like to ask regarding double sided setup. How do we change from probe ‘A’ to probe ‘B’ in the machine interface, is it under PART+WELD or SETUP? Since both probe need to calibrate, I can’t seem to find the option to change probe for setup

      Hi, Under setup, in group section you need to add GROUP. Each probe has to have individual group. Hope it helps.
