Custom Setups for Single Element Transducers
167
b)
Enter a
SETUP NAME
that describes the transducer and/or the application to
be used to create the setup.
c)
Set
MEAS TYPE
to the desired measurement type. The available choices are:
•
STANDARD
: For normal mode 1, 2, or 3 positive or negative peak
measurement.
•
FIRST PEAK
: For detection of the first of several peaks of similar
amplitudes (see “First Peak” on page 171 for details).
d)
Set
PROBE TYPE
to indicate the transducer type to be used with this setup.
The selected probe type must match the frequency of the transducer being
used for proper pulser/receiver performance.
e)
Set
VELOCITY
to the value of the sound velocity in the material that is to be
tested with this setup (see “Material Sound Velocity and the Zero
Calibrations” on page 59).
f)
Set
ZERO VALUE
to the calibrated zero-offset value (time of flight of the echo
that is not traveling through the material) for this transducer (see “Calibrating
the Instrument” on page 55).
g)
If needed, increase the
PULSER POWER
to increase the ultrasound wave
penetration in the material. Reduce the value for better near-surface
resolution (see “Pulser Power” on page 172 for details).
h)
Set
MAX GAIN
to the desired maximum gain value (see “Maximum Gain”
on page 174 for details).
i)
Set
INIT GAIN
to the desired initial gain value (see “Initial Gain” on
page 175 for details).
j)
Set
TDG SLOPE
to the desired time-dependent gain slope value (see “TDG
Slope” on page 175 for details).
k)
Set
MB BLANK
to the desired main bang blank time interval (see “Main Bang
Blank” on page 175 for details).
l)
Set
ECHO WINDOW
to the desired time interval (see “Echo Window” on
page 177 for details).
m)
Set
ECHO 1 DETECT
to
−
SLOPE
to detect the negative peak of the first echo,
or to
+SLOPE
to detect the positive peak of the first echo (see “Detection of
Echo 1 and Echo 2” on page 179 for details).
