12.9 Automatic Echo Optimization
The MAX II is equipped with a built in Auto Set feature for echo optimization. The
Auto Set uses a variety of algorithms, evaluating the positive and negative and
negative cycles, and selects the best phase (polarity) to use for measurement. It also
optimizes the gain, sets the delay and width, and activates and sets the gate
accordingly. Use of this feature will save the user a great deal of time in the
measurement process. In order to use the Auto Set properly, an approximate length
of the bolt must be entered into the MAX II. The approximate length tells the MAX II
where to start looking for the echo. The MAX II will search +/- 5% from the value
entered. The following procedures outline the Auto Set feature.
1) Press the MEAS key once to activate measure menu items. Press the
MEAS key multiple times to move down and the ESC key multiple times to
move up, until the ALEN cell is highlighted. Alternatively, press the
and DOWN arrow keys multiple times using the left button wheel.
2) Press the ENTER key to display the Digits Edit Box.
3) Press the
right button wheel to scroll the highlighted value.
4) Press the
button wheel to scroll the digit locations.
5) Repeat steps 3 & 4 until the ALEN value is correctly displayed.
6) Press the OK key to return to the measurement screen, or ESC to cancel
entering the ALEN.
