Use this to select the algorithm(s) the Sonic Intelligence echo selection is based on. Use
P805 Echo Confidence (page 69) to determine which algorithm gives the highest
confidence under all level conditions. If the wrong echo is processed, observe the echo
processing displays and select an alternate algorithm, either by entering the numeric
value desired, or as below:
1. Press MEASURE
2. Press ARROWS
