Ultrasonic Exam Calibration Guide

This document outlines ultrasonic examination calibration procedures for straight beam and angle beam transducers, including using thickness calibration blocks to set calibration ranges and locating reference signals, and calibrating the reference level using notched blocks on sample piping to determine sound path lengths and sensitivity settings. Procedures are provided for sweep calibration of straight beam transducers on IIW blocks and angle beam calibration in multiple positions, as well as calibration of the reference level DAC for ultrasonic testing of piping.
