Triton Isis - Manual (Page 157)

June 2004 Isis® Sonar User's Manual, Volume 2 147
• Altimeter: Determines whether the Altimeter transducer in the Klein towfish
is Active (transmits and receives) or Passive (receives only). See the Klein
manual.
I.5.2.3.2 Compute Depth from Voltage Panel
There are two values here. The first is the conversion from Voltage to Depth (m) for
the pressure sensor in the Klein towfish. The default value (41.208) is typical, but
your Klein 5000 manual might have a more accurate value that you could enter here.
The second value is the offset to correct from psia (absolute pressure) to psig (gauge
pressure). It is the value that will force the depth reading in the Isis parameter display
to be zero when the towfish is on deck. It should be around -9.8 m and will vary with
local weather conditions (average atmospheric pressure is equivalent to about 9.8 m
of water).
I.5.2.3.3 Diagnostics Panel
Two items are located in this panel:
Test mode and Transmit operator command.
Refer to the Klein 5000 manual for details before using these commands.
I.6 Reson Seabat 81xx Sonar
Selecting the Seabat 81xx option from the Select Sonar menu displays the dialog box shown
in Figure I-10.
