a. Note: A common action at this step is to tare the pressure sensor if required. This
is achieved by clicking the Gear Icon and selecting Tare Pressure Sensor.
9. The user is encouraged to explore the
Instrument Settings
page to familiarize
themselves with typical settings.
10. Optional: a common step for first time users is to commence real-time measurement
(data) streaming from the instrument. This is achieved through the
Live Data
tab in
Sailfish.
To disconnect the instrument unplug the USB-C cable or click the ‘Disconnect’ button.
2.2 Conducting a Profile
The typical workflow for conducting a profile is as follows:
1. Turn the instrument on and connect it to Sailfish using either WiFi (preferred) or USB-C
(refer Getting Started) and confirm the instrument’s battery status and configuration. Be
sure to tare the pressure sensor if required.
2. The instrument’s indicator LED will flash if it is attempting to acquire a GPS signal. If
GPS is locked, the instrument’s LED will turn solid. Refer the LED Flash Patterns in
Section 1.5 for more details.
a. Note that an instrument may be deployed without a GPS lock. Data will still be
logged, but the location data will be absent.
b. In the absence of a GPS lock, an instrument may be manually provided with GPS
coordinates in the
Instrument Settings
page.
3. If settings are correct, then ensure the instrument is ready for immersion by confirming
that the USB-C connector cover is in place.
Do not deploy the instrument without the
USB-C cover threaded completely onto the connector.
4. The instrument may be deployed at any time. If connected via WiFi, there is no need to
select the
Disconnect
button in Sailfish.
5. Lower the instrument into the water until its shackle sits just below the water line and its
indicator LED is visible. In most applications, the instrument is suspended by its shackle
from a downrigger, crab puller, or other mechanical device.
6. By default, the instrument will create a new log file and begin to record (log) data
automatically upon water detection.
a. Water detection is achieved by monitoring the measurements of an installed
Sound Velocity or Conductivity sensor. This behaviour is configurable through
advanced commands.
7. When in water and recording data, the instrument’s indicator LED will flash, confirming
operation. The instrument may then be lowered to the desired depth.
8. If the instrument was connected via WiFi then it’s connection to Sailfish will be lost (by
default, the instrument will turn its WiFi off when in water). Sailfish will recognize this
action and sit idle, awaiting for the instrument to return to the surface.
