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

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