12) Press the
and
arrow keys multiple times to scroll through the sub
menu items until
ULTRASONIC 1
is highlighted.
13) Apply a drop of couplant to the standard or transducer and attach it to one
end of the
3” calibration bar
.
14) Press the
key to display the measurement screen.
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.
15) Press the
key to automatically setup and measure the 3” cal bar.
Note:
Once an echo is found and the MiniMax is measuring the cal bar, the
GAIN, as well as the POLARITY may need to be adjusted. Using a large
diameter transducer can produce an extremely strong signal and often the
gain can be turned down to allow the user to see the peaks of the
waveform. A thorough understanding of the section on “Interpreting the
Waveform” is very important prior to making any adjustments.
16) Press the
and
arrow keys multiple times to scroll the hot menu
items until
ACCEPT CAL
is highlighted.
17) Press the
key to accept the calibration and return to the

19) Apply a drop of couplant to the bolt or transducer and attach it to one end of
the
6” calibration bar
. Use the 3” for the glass block.
