15) Press the key to automatically setup and measure the 3” cal bar.
Note: Once an echo is found and the MAX II 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.

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.
