11) Use the
UP
and
DOWN
arrow keys to scroll through the sub menu
items until
AUTO SET
is highlighted.
12) Apply a drop of couplant to the bolt or transducer, and attach it to one
end of the
3” calibration bar
.
13) Press the
ENTER
key and the
BOLTSCOPE PRO
will automatically
locate and measure the
Ultrasonic Length
of the first cal bar.
Note:
Rotate the transducer clockwise and counter clockwise applying a
small amount of pressure to eliminate any excess couplant between the
transducer and cal bar surface. Remove and replace the transducer a
couple of times in the exact same location on the cal bar, rotating it each
time to obtain the minimum value measured.
Be sure to always place the
transducer in the same location
.
This will help to eliminate any potential
measurement errors caused by changing the sound path.
Note:
Once an echo is found and the
BOLTSCOPE PRO
is measuring the
cal bar, the
GAIN
, as well as the
POLARITY
may need to be adjusted. The
cal bars produce an extremely strong signal and often the gain should be
set to the minimum 20dB depending on the diameter of the transducer. A
thorough understanding of the section on
“Interpreting the Waveform”
is
very important prior to making any adjustments. Once this section has
been reviewed, the
GAIN
and
POLARITY
features are located in the
TUNE
tabbed menu. Alternatively, the gain can also be adjusted in the hot menus
on the main measurement screen.
14) Press the
MENU
key multiple times to tab right and the
ESC
key
multiple times to tab left until the
CAL
menu is highlighted and
displaying the submenu items.
