Calibration
The TRIUMPH-LS is an
advanced scientific surveying
instrument. It is highly
sensitive to its environment
and includes a built-in
magnetometer and 3-axis accelerometer.
For the visual stakeout features and the
Ahead/Back
and
Right/Left White Boxes
in the
Stake Action
screen to
work correctly, the electronic compass readings need to
be accurate. It is recommended to check the compass
calibration before beginning work at a new location. To
check the calibration, rotate the TRIUMPH-LS 360° and
observe the compass readings in the
Collect
or
Stake
Action
screen. There should be no twitching, quick jumps,
or reversals of the displayed bearing or azimuth, just as a
real compass would perform. If this is not the case, the
compass needs to be recalibrated or it may not be in a
suitable environment for its use.
Follow the instructions on
the screen to calibrate the compass. When calibrating the
compass, choose an area removed from overhead power
lines, parked automobiles and other ferrous materials which
cause magnetic disturbance. The electronic compass works
in areas that are electromagnetically uniform.
The
Level
calibration typically only needs to be preformed
once. Follow the instructions on the screen to calibrate the
level.
The level sensors are sensitive to the internal temperatures
of the TRIUMPH-LS. To fine tune the level calibration, a
Level Offset
calibration needs to be preformed. It is located
in the
Action Setup
menu. It is necessary to reperform this
calibration as the internal temperature of the TRIUMPH-LS
changes.
If the
Correct For Tilts
option is enabled and the
most accurate positions are desired, it is essential to monitor
the
Level Offset
calibration and recalibrate when necessary.
The
Camera
needs to be calibrated if you intend to use the
camera’s
Visual Angle
or
Camera Offset Survey
tools. This
only needs to be done once.
Updates
Keeping your TRIUMPH-LS
up to date is nearly effortless;
however, you do need to
ensure that you have Internet
access in order to download the firmware and software
updates.
The TRIUMPH-LS will automatically detect nearby WiFi
networks. To see the detected networks, as well as their
respective signal strength, tap on the
WiFi
icon in the top
row of icons on the Home screen and then at the bottom of
that screen tap on Network. Select the desired access point,
tap on Connect, enter the case sensitive password, if any,
and the connection should be established. Once
connected to a WiFi network it will be remembered
and added to the Favorites and the connection to it
will become automatic when it is detected.
If you do not have WiFi or for some reason are unable to
connect to it, but do have a wired local area network, you
can connect the TRIUMPH-LS to your network using a cable
connected to the LAN port and your network interface card
or router. A wireless network can also be used if you have an
installed SIM card data plan with sufficient data.
Once connected to the Internet, J-Field will automaticaly
check for updates. The Support button will be displayed

Points
Screen Displaying Design Points
Each point record can have up to five types of coordinates
that are displayed in the
Edit Points
screen:
•
Design Coordinates
- Imported and manually entered
coordinates are populated into this field and stored in
the
Project
’s database file with their native coordinate
system as was selected when they were imported.
•
Survey Coordinates
- These are coordinates determined
from GNSS observation. All surveyed points are stored
with
Survey Coordinates
with WGS84 (ITRF 2008)
coordinates.
•
Base Station Coordinates
- When a point is surveyed
with RTK corrections, the base station coordinate is
saved.
•
Survey Shifted Coordinates
- When a point’s base
station coordinates have been adjusted or shifted, the
shifted survey coordinates are displayed along with
the unadjusted survey coordinates (
Survey Origin
).
•
Base Station Shifted Coordinates
- When a point’s base
station coordinates have been adjusted or shifted, the
shifted base station coordinates are displayed along
with the unadjusted base station coordinates (
Base
Station Origin
).
Edit Point

In addition to these coordinate types, all post-processed
DPOS and Real-Time Shifted coordinates are also stored in
the database. These will be discussed more in the DPOS
section of this manual.
