Field Practices
• Take comprehensive field notes.
• If it is not documented, it didn’t happen
• Take your time.
• Make sure you will record useful data.
The “Fort Five”
– Do you have power?
– Does the seismometer produce signal?
– Is your instrument programmed correctly?
– Do you have timing?
– Is your data being telemetered or stored on-site?

Things to Look For
• Last GPS Lock/Phase Error/Clock Quality
– GPS should cycle ever 3 hours
• Main Current/Input Volts
– Should usually be less than 100ma
– Input Volts should be >12V
• Boom Pos (in 1/10V, e.g. 18=1.8V)
– Should be between -20 & +20
• Last Boot
– Should coincide with your last service or earlier
• Last Resync
– Last time the internal clock was significantly different from
GPS time and internal clock had to be resynchronized. This
should usually only happen shortly after Last Boot time.
Check the Sensor
• Select QuickView
beneath the Views
menu.
• Do a Stomp Test to
ensure all elements are
working
• Be sure to press Stop
before leaving this
window.
Flush RAM to baler
• If the Status LED is green and the Ethernet Link LED is
on then the baler is already running. If the Ethernet
Active LED is yellow most of the time it means that
data is being sent to the baler. Wait until the Ethernet
Active LED activity slows down then press and release
the ATTN button to turn the baler off. Wait until the
Status LED returns to blinking green every few seconds
before doing anything else.
• If the Status LED is blinking once every few seconds
then the baler is off. Use the menus below to turn the
baler on.
Downloading Baler Data
Prepare the Baler
• Using the download
QNET cable, connect the
alligator clips to a
battery.
• Connect the RJ-45 to the
laptop.
• Connect the QNET
connector to the front of
the Baler
Note: This is a cross-over
network cable.
