Software Features and Options 241
To setup DGS/AVG curves on the instrument very quickly, Olympus has developed a
transducer library that is stored in the instrument’s memory. This library contains the
entire Atlas Series European specification conventional transducers as well as several
other transducers that are commonly used by inspectors. The library includes five
categories:
• Straight Beam contact (includes protected face)
• Angle Beam transducers
• Dual Probe transducers
• Custom Straight contact
• Custom Angle beam
All required data for building DGS/AVG curves is stored in instrument memory for
each transducer in the library. If you want to use a probe that is not in the default
library, you can enter the required transducer characteristics in the GageView Pro
computer interface program and download them to the EPOCH 650. Probes that are
downloaded to the instrument appear in the custom transducers section of the
transducer library.
The onboard DGS/AVG option provides you with rapid setup times and easy flaw-
size evaluation. This software option has been designed to meet the ISO 16811:2014
requirements. It is extremely important that you be familiar with this specification
and others, and be qualified according to local standards to properly use this
instrument function. Since the curves used for defect sizing are calculated based upon
many variables, a proper instrument setup is required for accurate results.
11.3.1 Option Activation and Setup
Before activation of the DGS/AVG option, the instrument must be properly calibrated
to the material being inspected (see “Calibration” on page 143).
To activate the DGS/AVG option
1. Choose DGS/AVG > Setup to display the AVG setup page (see Figure 11-14 on
page 242).
