9.8. Selecting AUTO TVG Characteristics for 50 & 200 kHz Transducers
Figure 9-8 Selecting Auto TVG Characteristics – Example
・
To take full advantage of the automatic TVG
function, two sets of initial gain suppression
curves (initial gain suppression level–versus–
depth or TVG response characteristics) are
incorporated and optimized for each of the
approved 50 kHz and 200 kHz transducers.
・
Selecting option “ 7: AUTO TVG RESPONSE ”
displays the list of the transducers that can be
used for your echo sounder, as in the example
at right.
・
The following procedure assumes that a TOKIN
50 kHz transducer
( TGM60–50 series)
is mounted
in your installation.
(1) Select option “ 2:TGM–60–50 ” by pressing

(numeric key “ 2 ”)
.
(2) Press

to complete the selection. The SYSTEM MENU should then return.
(3) Press

to return to the normal echogram screen, unless you wish to make additional
settings on the SYSTEM MENU .
・
In the case of 200 kHz installations, the menu options displayed will be "1:LSE 313"
and " 2:TGM–80–200 . " If your system uses a TOKIN 200 kHz unit, choose
“ TGM–80–200 .”
・
For installations using 100 kHz transducers, the AUTO TVG RESPONSE submenu will
not be displayed. All approved 100 kHz units carry the same response characteristics.
