The EPOCH 1000 Series can also transfer inspection data to the GageView Pro
computer interface program to aid in report generation. This program allows the
inspector to view the instrument’s setup parameters, the waveform generated by a
discontinuity, the discontinuity’s sound path and location information, and all values
for the AWS D1.1 formula variables.
11.4.2 Option Activation
The first step in operating the EPOCH 1000 Series for AWS D1.1 inspections is to
calibrate the instrument for the transducer and test conditions. For information on the
angle beam calibration of the EPOCH
1000 Series, see the calibration section of this
manual or the appropriate guidelines from the American Welding Society.
To activate the AWS software feature
Select 4/6 > Sizing Option > AWS D1.1 = On.
After activation, you must set a Ref B value in order to begin an inspection. This
number represents the gain level necessary to bring the echo from a reference-
reflector to 80
% full-screen height (FSH). The reference-reflector is often a side-drilled
hole in the calibration block used for the angle beam calibration. Other reference-
reflectors can be used provided that they meet AWS requirements for these
inspections
To store a Ref B value
1. Use the [GATE] key to gate the echo from the reference-reflector.
2. Press [2
ND
F], [GATE] (AUTO XX%) to bring the echo to 80 % FSH.
3. Choose 6/6 > AWS > Ref B to store the gated reflector as the Ref B value.
