P820 ALGORITHM
Use this feature to select the
Algorithm(s)
(mathematical operations) which the Sonic
Intelligence
TM
echo selection is to be based on.
This value is automatically altered by Material (P002).
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)
The material/vessel type most likely to benefit from a particular algorithm is included with
the following option values.
values: ALF = long range Area, Largest, and First average (general purpose, solids)
A = long range Area only (coarse, heaped solids)
L = long range Largest only (liquids, open vessels)
F = long range First only (liquids, closed vessel)
AL = long range Area and Largest average (fine heaped solids)
AF = long range Area and First average (coarse flat solids)
LF = long range Largest and First average (general purpose, liquids)
bLF = short range Largest or First (general purpose)
bL = short range Largest only (solids and open vessel liquids)
bF = short range First only (closed vessel liquids)
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 an echo from a partial transducer
beam obstruction (seams, ladder rungs, etc.) 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
