Part 11: Station Servicing & Data Offload

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?

• Select System from Views

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.
