P820 Algorithm

Chooses the algorithm to generate the measured value from the profile.

Primary Index		Single Point Model					Dual Point Model

	Global						Transducer
	Global						Transducer

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

	9				bL = smooth Largest only

	10				bF = smooth First only

	12				tF = true First only

	•	P805		Echo Confidence
	•	P821		Spike Filter
Related	•	P822		Narrow Echo Filter
	•	P823 Reform Echo
	•	P825		Echo Marker Trigger

Use this to select the algorithm(s) the Sonic Intelligence® echo selection is based on. Use P805 Echo Confidence (page 202) 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 to display the Auxiliary Function symbol.

2.Press ARROWS to access the desired Reading display symbols.

3.Press ENTER when the required algorithm is displayed.
