• Gate Control
Gate 1 and 2 parameter adjustments are limited to gate start. Because the
precision mode measurement algorithm is not dependent on gate level, the gates
are fixed at the top of the A-scan. G1 Start acts as a blanking function to help
detect valid echoes when material conditions generate unwanted signals.
•Grid View
When grid view is active, the grid displays in precision mode, and navigation
arrows are located in the sidebar menu.
11.7.3 Corrosion Module Activation and Setup
If an Olympus thickness gage dual transducer is connected to the instrument when
the corrosion module is first activated, the transducer parameters load automatically,
and the identified transducer is indicated at the bottom of the screen.
If an Olympus thickness gage dual transducer is not connected to the instrument
when the corrosion module is first activated, the Transducer Setup page is displayed.
With this page, you select the dual transducer you want to use for the inspection.
Then the key parameters for the transducers are loaded with default values.
To activate the Corrosion Module
1. Connect an appropriate transducer to the EPOCH 6LT.
If an Olympus thickness gage dual transducer is connected to the EPOCH 6LT, a
dialog box will prompt you to press the Enter key to continue (see Figure 11-33 on
page 194).

2. On the setup menu, select the Tools icon ( ) to open the Tools submenu (see
“Setup Mode” on page 17 for details on icons and submenus).
