P820 ALGORITHM
Use this feature to select the
Algorithm(s)
(mathematical operations) which
the Sonic Intelligence
TM
echo selection is to be based on.
If the wrong echo is processed, select an alternate algorithm, while
observing the resultant echo processing displays.
To select an Algorithm...
1. to display the Auxiliary Function symbol,
2. or to display the desired Reading display symbol(s),
3. (when the desired Algorithm is displayed)
Alternatively, enter the value desired.
values: 1 = ALF = flat Area, Largest, and First average
2 = A = flat Area only
3 = L = flat Largest only
4 = F = flat First only
5 = AL = flat Area and Largest average
6 = AF = flat Area and First average
7 = LF = flat Largest and First average
8 = bLF = smooth Largest or First (preset)
9 = bL = smooth Largest only
10 = bF = smooth First only
P821 SPIKE FILTER
Activate the Spike Filter if interference spikes are observed on the long
shot Echo Profile display.
values: 0 = off
1 = on (preset)
P822 NARROW ECHO FILTER
Use this feature, when monitoring solids (P002 = 2) only, if transducer
acoustic beam interference (e.g. ladder rungs) is processed.
Enter the width of false echoes (in ms), to be removed from the long shot
Echo Profile.
When a value is keyed in, the nearest acceptable value is entered.
values: 0 = off (preset), greater = wider
