Smart Systems User’s Manual Version 1.1

5.2.1 Section A - Data Parameters
Section A displays three items:
1) The total depth to the bottom of the data image in Section B,
2) The velocity used to calculate the total depth and the depth lines (see
Depth Lines in Section 5.2.2) and
3) The position indicator in meters or feet (depending on the odometer units
set, see Section 5.5.1 – Units).
Rather than displaying total depth and depth lines the user can select to display the total
time window in nanoseconds (see Section 5.5.1 - Units).
Note that it is possible to change the position label size (see Section 5.5.1 – Label Size).
5.2.2 Section B - Data Display
This section contains the actual data collected or replayed. The section also contains the
depth indicator lines, battery voltage indicator (which is visible each time you start), start
of section indicators, and any fiducial markers the user enters. See the sections below
for more details.
Depth Lines
Depth lines are horizontal labelled lines indicating the estimated depth. They are very
useful for getting depth estimates to features of interest in the data.
The positions of the Depth Lines are controlled by the current velocity value as well as
the depth selected. See Section 5.3.5 on selecting different depths and Section 5.8.1 for
more details on how depths are determined.
To display the correct depth, it is the responsibility of the user to calibrate the
system to the correct velocity of the material (see Section 5.3.4 on how to
calibrate the system).
Note that it is possible to change the depth units and the depth label size (see Section
5.5.1).
Battery Voltage Indicator
When the Start button is pressed, the current battery voltage will be displayed on the
extreme left side of the screen.
The voltage indicator can be helpful for identifying when the battery needs to be
recharged. If the battery voltage drops below 10.5 volts the DVL will cease to operate
and this monitoring capacity will not be available.
