Calibrating the EPOCH 1000 Series (Conventional UT Mode) 135
Use more range than necessary to ensure all calibration echoes appear on the
screen.
5. Choose 1/5 > Basic > Delay, and then set the screen delay to 0.000 in. or 0.00 mm.
6. Choose 1/5 > TRIG > Angle, and then enter the correct refracted angle for the
probe (0 for a straight beam or 90° probe, 45 for a 45° probe, etc.).
7. Choose 1/5 > TRIG > Thick, and then set the material thickness to 0.00 in. or
0.00
mm.
8. Choose 1/5 > Receiver > Reject, and then set the reject level to 0 %.
9. Select 2/5 > Gate 1 > Status = On to activate gate 1.
10. Couple the transducer to the block, and then adjust the pulser and filter settings
to create a clean A-scan.
For more information on pulser and receiver adjustments, see section 4.4 on
page 92 and section 4.5 on page 96.
Use the auto measurement reading selection feature so that the EPOCH 1000
Series automatically displays relevant thickness/sound path measurements
during calibration based on the instrument settings. For more information, see
section 3.3.3 on page 71.
9.2 Calibration Modes
The EPOCH 1000 Series features multiple calibration modes to accurately meet the
requirements of the selected transducer, calibration test block, and application. These
calibration modes can be adjusted in the 1/5
> Auto CAL submenu. There are two
modes for straight beam transducers and two modes for angle beam transducers.
