Calibration for external system transducer
The calibration procedure for external echo sounder is different from the FCV-2100.
There are two method, depending on equipment configuration.
External Echo Sounder mode is ‘Off’
1. Select the [Advanced Settings] icon (
) from the InstantAccess bar, and se-
lect the [Advanced Setting] icon (
) from the expanded menu bar.
[Bottom Lock
Mode]
[Level],
[Color]
Set how the bottom edge is determined, by
signal level or display color.
• [Level]: Determine the bottom edge by sig-
nal level. When the method is [Color], bot-
tom fish may be hidden in the bottom edge.
With [Level] the shape of the bottom echo
may change depending on the bottom con-
tour of the bottom.
• [Color]: Determine the bottom edge by dis-
play color. When bottom fish are well sep-
arated from the bottom, the bottom is
displayed with a straight line, making dis-
crimination of bottom fish easier. However,
the bottom presentation may change de-
pending on gain setting. When set to Color,
select the color (0-63) to be judged as the
bottom echo.
[Bottom level]
[-40] to [40]
(default: [0])
Set the strength at which an echo is deter-
mined to be the bottom. If the level is too low,
however, it may be difficult to distinguish bot-
tom fish from the bottom echo.
[Bottom Color]
[0] to [63]
(default: [50])
Set the color for the bottom.
[Zero Line Fill]
[Off],
[On] (default)
Turn off to see fish echoes within 1 m from the
surface.
[Draft]
[m]: -9.0 to 30.4
[ft]: -30.0 to 99.9
[fm]: -5.0 to 16.6
[HR]: -6.0 to -20.1
[pb]: -6.0 to -18.8
(default: 0.0)
The default depth display shows the distance
from the transducer. If you would rather show
the distance from the sea surface, set your
ship’s draft. The draft line for HF and LF can
be set respectively.
[Gain ADJ]
[-50] to [50]
(degfault: [0])
If the gain is too high or too low, or the gain for
the low and high frequencies appears unbal-
anced, you can compensate it here.
