1. Phased Array Operation—Keypad, Menus, and Displays
The Phased Array Home Menu System consists of several
menus, submenus, and functions.
•
If not displayed, phased array mode is activated by
first pressing
, then selecting PHASED ARRAY.
•
Available menus are accessed via the phased array
Home Menu
(Figure
•
Each menu contains several submenus.
•
Menus and submenus are selected by pressing
below the desired item.
•
When a submenu is selected, the functions con-
tained in that submenu are listed in the Function Bar
down the left-hand side of the display screen.
•
Functions are then selected by pressing the
adjacent Function Key
•
Turning the Function Knob, and in some cases
continuing to press
in the selected function's box. Pressing and holding
will set some functions to zero.

•
ORIGIN OFFSET—Defines the distance from an artificially desig-
nated zero position (such as the center of a weld) to the projection
point of a reflector in the gate. Setting equal to zero sets the probe's
front edge as the zero position.
PART MENU
PLAN Submenu (Refer to
Section 2.4)
•
VELOCITY L— Longitudinal velocity of sound in the part under test
•
VELOCITY S—Shear (Transverse) velocity of sound in the part
under test
•
MAT THICKNESS—Thickness of part under test
•
MATERIAL—Select the material being tested and the typical sound
velocities (for both longitudinal and shear waves) are automatically
entered. The correct values will be determined during calibration.
CAL Submenu (Refer to
