Downloading Wirelessly
Wireless downloading of fusion data is handled entirely through the EF Technologies app (EF Utilities).
Turn the processor ON. Allow it to proceed through the INTERNAL SELF TEST to the CONNECT FITTING screen
before attempting a download. All progress indications and user feedback are communicated through the
app.
GPS
The optional GPS in the
SMART Scanner™
can be used to record the latitude and longitude of the processor
where the fusion is done.
•
The GPS coordinates are accurate to within 10-15 meters.
•
The latitude and the longitude, as well as the number of satellites used when generating the fix, are
stored with each fusion and output during the download.
•
Once downloaded, the coordinates can be input into many commercially available mapping programs
to obtain position information.
Trouble
The most common cause of GPS signal trouble is poor signal quality. This may be caused by:
•
Antenna orientation.
•
Obstructions such as buildings or trees.
•
Weather conditions.
Other than moving the receiver or waiting for the weather to clear, there is not a great deal of control that
one has over a poor signal. Be sure to hold the device with the antenna (the side with the sticker) pointing up
and with a clear view of the sky.
When the device is in the CONNECT FITTING
screen, the “
-
“
in between the latitude and the longitude
measurement will flash. This flashing indicates that the
SMART Scanner™
is receiving a signal from the GPS. If
this dash is not flashing, there is a problem with the GPS receiver itself and it should be returned.
Position Accuracy
GPS accuracy is affected by a number of factors, including satellite positions, noise in the radio signal,
atmospheric conditions, and natural barriers to the signal. Noise can create an error between 1 to 10 meters
and results from static or interference from something near the receiver or something on the same frequency.
Objects such as mountains, buildings, or even clouds in between the satellite and the receiver can also
produce an error, sometimes up to 30 meters. The most accurate determination of position occurs when the
satellite and receiver have a clear view of each other and no other objects interfere.
THE SMART SCANNER™ WAS NEVER DESIGNED TO GIVE A POSITION ACCURATE EN
OUGH TO GO FIND A
FITTING AND DIG IT UP. IT IS PROVIDED TO ALLOW THE OPERATOR TO DETERMINE THE GENERAL LOCATION
WHERE THE FITTING CAN BE FOUND.
