Setting the Probe Delay (PROBE-OFFSET-PROBE
DELAY)
The Probe Delay Setting represents the time delay caused
y sound-wave travel through a probe’s wearplate, mem-
brane, delay line, or wedge. The Probe Delay value is set
as part of the Calibration process (section 2.9). To adjust
the probe delay:
Step 1:
Activate the OFFSET Submenu (Located in the
PROBE MENU) by pressing below it. Selections will
appear down the left side of the display.
Step 2:
Press
next to PROBE DELAY.
Step 3:
Turn the Function Knob to adjust the PROBE
DELAY setting.
2.3.3 Inputting Wedge-Related
Information
If the connected phased array probe is equipped with a
wedge, wedge-related settings must be input by accessing
the PROBE Menu (
Figure 2-3
). These settings must be
adjusted each time a different wedge is connected. Most
of the wedge-related data is printed on its surface. Note
that all wedge-related settings can be stored in a data set
file as described in
Section 6.1
.
Inputting Wedge Part and Serial Number
(PROBE-WDGE DAT-PART or SERIAL NUMBER)
Step 1:
Activate the WDGE DAT Submenu (located in
the PROBE Menu) by pressing
below it.
Step 2:
Press
next to one of the selections (PART
NUMBER or SERIAL NUMBER) two times. The cursor
will illuminate in the first-digit space.
Step 3:
To change the value of the active digit of the part
or serial number (to match the value printed on the side
of the probe connector), turn the Function Knob. To make
the next digit active, turn the Gain Knob.
Step 4:
Press
again to complete the PART or
SERIAL NUMBER entering process.
The orientation of probe elements with respect to the
wedge is displayed on the next page.
Defining the Wedge Geometry (PROBE-WDGE
GEO-VELOCITY or OFFSET Z or ANGLE)
Step 1:
Activate the WDGE GEO Submenu (located in
the PROBE Menu) by pressing
below it. Selections
will appear down the left side of the display.
Step 2:
Press
next to one of the selections
(VELOCITY or OFFSET Z or ANGLE).
Step 3:
To change the displayed value (to match that
printed on the wedge), continue pressing
or turning
the function knob. You’ll note that the following settings
are available (
Figure 2-4
):
VELOCITY – Input in/microseconds to match the
velocity of sound through the wedge material
OFFSET Z – Input inches / mm (must be set to 0
when no wedge is installed) to equal the user-mea-
sured dimension from the wedge surface in contact
with the test piece to the Probe Index Point.
ANGLE – 0.0 to 90 degrees to match the user-mea-
sured wedge angle.
Step 4:
The selected parameter will be set to the value
last displayed. Recalculation of delay laws is required.
FIGURE 2-4—Wedge Geometry is defined here. Manually measure the distance from the Probe Index Point to the front
of the wedge to find the WEDGE FRONT value. You must determine this value whenever ORIGIN OFFSET techniques
are used.
