Simrad PI SEINESOUNDER TRAWLERS - QUICK REFERENCE GUIDE REV B Quick Reference Manual page 2

Numerical presentation
On the PI display, you must use two
channels to receive the information
from the SeineSounder. The depth
and height values are then shown in
the numeric display. If the height or
depth is increasing or decreasing, this
is shown with two arrows and the
variation in meters per minute.
You can also see the depth and
height changes as a function of time in
a graphical presentation.
When the readings are stable, the
digits are shown in black colour. If the
contact is lost, the characters *** are
shown in grey. If the height is out of
range, the displays shows ???.
Mounting
Location: Place the sensor where
you wish to monitor the height. This
is normally aft of the headrope at the
center of the net.
