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
