3.9. Sensor Commands
Sensor commands output data from the ADVField’s optional internal sensors: temperature, pres-
sure, and battery voltage. Additionally, a variety of optional external sensors can be controlled
through the direct command interface.
3.9.1. Internal Sensor Commands
Sensor [CONT]
• Without parameter: Display once the current temperature (°C), pressure (dBar), and battery
voltage (VDC) data.
• With
CONT parameter: Display continuously (updated twice per second) the temperature
(°C), pressure (dBar), and battery voltage (VDC) data. Press any key to stop data output and
return to command mode.
• Data is output in a self-explanatory, ASCII-text format.
• Note: If
ExtSensor = 3_OBS , the pressure and battery voltage readings will display N/A .
PressScale
• Displays the pressure-scaling factor used to convert counts to dBar. The scaling factor is
shown in units of dBar/count (see §4.8 for data conversion details).
PressOffset
• Displays the pressure offset used to convert pressure counts to dBar. The offset is shown in
units of dBar (see §4.8 for data conversion details).
3.9.2. External Sensor Commands – Overall Control
These commands are common to all external sensors.
ExtSensor [NONE|STANDARD|3_OBS]
• Without parameter: returns current setting.
• When used with a valid parameter, tells the ADV processor what type of external sensor(s)
are installed.
○ NONE – No external sensors are installed.
○
STANDARD – One or two of the more typical external sensors is installed: SeaBird Micro-
Cat CTD (§3.9.3), a resonance pressure sensor (§3.9.4), a LISST sensor (§3.9.5).
○
3_OBS – Three external sensors are installed. Note that with this option selected:
!
Sensor [CONT] will display pressure and battery voltage readings as N/A .
! The real-time and deployment extraction software will store the Channel 3 sensor data
in the pressure column, but will not apply any pressure scaling to the data.
3.9.3. External Sensor Commands – SeaBird MicroCat CTD
H CTD
• Displays help information for the CTD commands.
CTD [CONT]
• Without parameter: Display once the most recent temperature (°C), conductivity (Siemens
per meter), pressure (decibar), and salinity (ppt) from the external CTD sensor.
• With
CONT parameter: Display continuously temperature (°C), conductivity (Siemens per
meter), pressure (decibar), and salinity (ppt) from the external CTD sensor. Press any key to
stop data output and return to command mode.
