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).
6. Press [SAVE].
7. In the SAVE SETUP screen:
a) If needed, in the SAVE AS dialog box, edit the setup name.
b) In the SAVE TO list, select the desired custom setup location in which you
want to save the setup.
