When API 5UE is activated, the function keys on the EPOCH 650 aid the inspector in
collecting calibration and inspection data. Also, the AUTO XX% feature allows you to
automatically bring any captured echo to 80 % of FSH, which is particularly helpful in
obtaining a precise A reading from a reference notch.

The API 5UE code specifies that before inspection, the instrument must be calibrated
using a reference notch of known depth (in certain circumstances, a through-drilled
hole is desirable for calibration – see the full text of the API Recommended Practice
5UE for details concerning reference standard selection). The depth of this reference
notch must be entered correctly in the activation menu for the API 5UE software
option.
Before calibrating with a reference notch, the instrument should be calibrated to
verify beam index point, refracted angle and distance in the inspection material. See
"Calibrating to Known Sound Path Values with an Angle Beam Transducer" on
page 165 and "Calibrating to Known Depth Values with an Angle Beam Transducer"
on page 175 for details regarding angle beam calibration.
