2.4.2 Angle Beam Calibration
Angle beam calibrations typically require four steps. Each step is outlined below:
To perform angle beam calibration
1. Verify the Beam Index Point (B.I.P.).
2. Verify the refracted angle of wedge.
3. Complete the distance calibration using steps of section 2.4.1 on page 39
( Calibration mode set to SoundPath or Depth depending on the reflector type).
4. Set the sensitivity by capturing sensitivity hole or notch in gate 1, bringing the
indication to 80 % screen height using (AUTO XX%) , and then setting the
reference gain by pressing [2
ND
F] , (REF dB) [see Figure 2 ‐ 18 on page 43].

2.5 Data Logger
The EPOCH 600 features an onboard data logging system that allows standard
storage of inspection files (Inc) and dedicated calibration files (Cal), as well as
optional inspection files in corrosion style configurations (2D, 3D, Boiler, etc).
Regardless of file type, each discrete data point saved on the EPOCH 600 stores all
