echo reports, then press ↓ to scroll through the echo
reports. The echo report is described on page 5-11.
echo amplitude
successive weighting
factor(SWF)=.5000
NEXT↓↓ HELP→→
The successive weighting factor is applied to the
signal strength of each echo before it is compared to
the next closer echo. The same weighting factor is
used for each echo. This is part of the process of
selecting the “best candidate.”
Direct Entry Code: ‘007003’
Minimum allowable
signal strength
3.000
NEXT↓↓ HELP→→
Only echoes with a signal strength equal or greater
than this value will be reported as a possible
candidate.
Direct Entry Code: ‘108003’
maximum desirable
signal strength
0.000
NEXT↓↓ HELP→→
If this variable is set to 0.000 (default), the gauge will
not use this function to reject echoes. If this variable
is set to a non-zero value, the gauge will reject any
echo greater than this value unless there are no other
candidates. Used to reject strong unwanted echoes.
Warning: If the desired echo exceeds this setting,
the desired echo will be rejected unless
it is the only candidate echo.
Direct Entry Code: ‘104003’
maximum echo count
to be processed 8
NEXT↓↓ HELP→→
This item limits the number of echoes which the
gauge will process. Enter a value between 1 and 24.
For the default value of 8, the strongest echoes (up to
8 maximum) which exceed the minimum allowable
signal strength and which fall within the ROI are
reported as candidate echoes.
Direct Entry Code: ‘025004’
Reject echoes with
Q1 below 0
NEXT↓↓
[Service only item]
Enter minimum value for quality factor Q1 (0 - 255).
If a non-zero value is entered, any candidate echo
with a Q1 value less than this minimum value will be
rejected. A 0 entry (default) disables the rejection of
candidate echoes based on the Q1 value.
Direct Entry Code: ‘043004’
Reject echoes with
Q2 below 0
NEXT↓↓
[Service only item]
Enter minimum value for quality factor Q2 (0 - 255).
If a non-zero value is entered, any candidate echo
with a Q2 value less than this minimum value will be
rejected. A 0 entry (default) disables the rejection of
candidate echoes based on the Q2 value.
Direct Entry Code: ‘044004’
