Sensor Filter
The
Sensor Filter
can be used if you have problems with the reception. It will average
the data received from the sensors. After the sensors have been submerged, the
receiver requires only three consecutive pings from individual sensors to calculate and
display their respective information. However, if you experience problems with the
reception, you may try this filter.
The
Sensor filter
offers four different settings.
•
Off
The
Sensor filter
is switched off.
•
Weak
The information from the last four sensor transmissions are averaged.
•
Medium
The information from the last eight sensor transmissions are averaged. This has
proven to be a useful setting for trawlers.
•
Strong
The information from the last 16 sensor transmissions are averaged.
The default setting of the filter is Weak .
Catch filter
This is a median filter. The
Catch filter
reduces the jumping between “catch” and “no
catch” states. This will reduce jitter in the presentation.
The
Catch filter
offers four different settings. The default setting of the filter is Weak .
• In Off mode, the filter is disabled.
• In Weak mode, the data from the last three sensor transmissions are median filtered.
• In Medium mode, the data from the last five sensor transmissions are median
filtered.
• In Strong mode, the data from the last seven sensor transmissions are median
filtered.
