EAR-Controlled Technology Subject to Restrictions Contained on the Cover Page.
ES – Salinity
Purpose
Sets the water’s salinity.
Format
ESnn
Range
nn = 0 to 45
Default
ES35
Recommended Setting. Set using
Plan
. The default setting for this command is recommended for most
applications.
Description ES sets the water’s salinity. The Sentinel V Real-Time uses ES in its speed of sound calcula-
tions. The Sentinel V Real-Time assumes the speed of sound reading is taken at the trans-
ducer head.
ET – Temperature
Purpose
Sets the water’s temperature value.
Format
ET±nnnn
Range
±nnnn = -500 to 3500 (-5 to +35C)
Default
ET2500
Recommended Setting. Set using
Plan
. Use the EZ-command to default to the sensor module.
Description ET sets the temperature value of the water. The Sentinel V Real-Time uses ET in its speed
of sound calculations (see the primer). The Sentinel V Real-Time assumes the speed of
sound reading is taken at the transducer head.
Example
Convert temperatures of +14 C and -3.5 C to ET-command values.
ET = 14.00 × 100 = 1400 = ET1400 (+ is understood)
ET = -3.50 × 100 = -350 = ET-0350
If the EZ Temperature field = one, the Sentinel V Real-Time overrides the manually set ET
value and uses temperature from the transducer’s temperature sensor. If the sensor is not
available, the Sentinel V Real-Time uses the manual ET setting.
EU – System Orientation
Purpose
Sets the Sentinel V Real-Time system orientation, up or down.
Format
EUn
Range
n = 1 (up), 0 (down)
Default
n = 0
Recommended Setting. Use the EZ-command to default to the sensor module.
Description EU sets the Sentinel V Real-Time system orientation, up or down.
If the EZ Roll field is not zero, the Sentinel V Real-Time overrides the manually set EU value
and uses orientation from the transducer’s internal tilt sensor. If the sensor is not available,
the Sentinel V Real-Time uses the manual EU setting.
