SBE 21 Thermosalinograph Configuration
Time between scans. Used to calculate elapsed time,
if you select time as a parameter for a display
window. Must agree with number programmed into
SBE 21 with SI command; see reply from status
command (DS).
Select if Interface Box
connected to NMEA navigation
device. SEASAVE adds
current latitude, longitude, and
universal time code to data
header; appends NMEA data
to every scan; and writes
NMEA data to .nav file every
time Ctrl F7 is pressed or Add
to .nav File is clicked (see
Adding NMEA Data to .nav File
in Section 8: Real-Time Data
and Real-Time Control - Real-
Time Data Acquisition).
Click a sensor
and click Modify
to change
calibration
coefficients for
that sensor.
New to create new
.con file for this CTD.
Open to select
different .con file.
Save or Save As to
save current .con file
settings.
Opens a .txt file (for viewing
and printing only; cannot be
modified) that shows all
parameters in .con file.
Shaded sensors cannot be removed or changed to
another t
yp
e of senso
r
. All others are o
p
tional.
Click to exit dialog box. If you made changes and did
not Save or Save As, SEASAVE asks if you want to
save changes.
Channel/Sensor table reflects this choice (shows
additional frequency-based temperature channel
if SBE 3 selected, or RS-232 channel if SBE 38
selected). Must agree with SBE3= or SBE38=
command programmed into SBE 21 to enable or
disable external temperature sensor; see reply
from status command (DS).
If remote temperature is selected, SEASAVE
(and Data Conversion and Derive in SBE Data
Processing) uses remote temperature data when
calculating density and sound velocity.
Channel/Sensor table reflects
this choice. Must agree with
number programmed into
SBE 21 with SVx (x=0, 1, 2, 3,
or 4) command; see reply from
status command (DS). Voltage
channel 0 in .con file
corresponds to sensor wired to
channel 0 on end cap
connector, voltage channel 1 in
.con file corresponds to sensor
wired to channel 1 on end cap
connector, etc.
Click a (non-shaded) sensor and click Select to pick a different sensor for
that channel. A dialog box with a list of sensors appears. Select sensors
after number of voltage and frequency channels have been specified above.
Select if Interface Box connected to NMEA depth device.
SEASAVE appends 3 bytes of depth data to every scan, after
Lat/Lon data. NMEA depth data can be selected only if NMEA
position data added is selected.
