Enhancement Parameters
P820 ALGORITHM
Use this feature to select the
Algorithm(s)
(mathematical operations) which the
Sonic Intelligence® 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 perform the following steps:
1. Press to display the Auxiliary Function symbol.
2. Press or to display the desired Reading display symbol(s).
3. Press (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
A
L
F
AL
AF
LF
bLF
bL
bF
= long range Area, Largest, and First average (general
purpose, solids)
= long range Area only (coarse, heaped solids)
= long range Largest only (liquids, open vessels)
= long range First only (liquids, closed vessel)
= long range Area and Largest average (fine heaped
solids)
= long range Area and First average (coarse flat solids)
= long range Largest and First average (general purpose,
liquids)
= short range Largest or First (general purpose)
= short range Largest only (solids and open vessel liquids)
= 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
