Take and connect handheld to gps. Within a minute or so verify connections and turn gps on.

1 tribrach Gps Hand held Comm cable Power cable

Watch out for hitting the power button on the trimble handheld.

Middle icon is for radio (rtk) Slow / steady flash is good rapid flash is not so good. Solid green means the memory is full.

Hold power for just a few seconds to turn gps and handheld off. 15 s equals factory reset. Hold the power on the handheld down until it makes a sound. A message will appear telling you that you can release the power button. If you do not release the power button it will do a hard reset.

Extend the tripod legs until the tripod platform is even with face. Do the initial level by eyeball. Put the tribrack on and check to see that the gps is centered over the benchmark. If it isn't, use your foot as a guide and look through the aiming site until the tripod is roughly centered over the benchmark. The lines on triBarach leveling are roughly at midpoint. Before doing final leveling, reset to midpoint.

Then site through optical plummet. Optical deal has a focusing ring so if things are fuzzy... Also watch out for parralax. There's a ring for that, too.

One thing he'll do is figure out where the toe is and then guide it in with th toe.

Once over relevel. Get a bubble near one leg Finish the leveling

Look for 5/8ths rebar (and center over that, may or may not be a cap over it.). Rebar is the monument for this project.


Survey Controller is program on handheld.

Measure from center of bumper (a choice) and from the bottom of gps to the benchmark.

Note the serial number in notes

Receiver file location:

Jobs: Gage10 should be the active job. If it's not: 1) Single click 'files' in upper left corner 2) Click 'open job' from context menu 3) Select 'GAGE10' as the job. Click it once and then click 'select' in lower right corner.

Next up download the data. It will be found on the handheld here: Trimble/disk/trimble data/

To download the data: 1) Wait for the instrument to appear on the right hand icon area. You should see two sets of battery informations when the handheld is communicating with the gps. 2) Click 'Instrument' 3) Click 'Receiver files...' 4) Click 'import from receiver' 5) Click on the file e.g. '13531560' and click import. 6) It will take a really long time to import. It's a good idea to keep the handheld warm for the battery so stick it inside your jacket and check on it occasionally. 7) Once it has downloaded verify you have the file by exiting the survey controller program and once at the homescreen double click 'my computer' 8) Navigate to '/disk/trimble data/'. You should see the file here for example '13531560' the modified date should be when you downloaded the data. The size should be a bit over 42MB if you let it log until the memory was full. 9) After verifying the presence of the file, exit the file explorer and start the Survey Controller again. 10) After the handheld has found the gps again click on 'instrument' 11) Click on 'receiver files...' 12) Click on 'import from receiver' 13) Select any files on the gps and delete them using the 'delete' button along the lower edge of this screen. These files are being deleted off the gps, not the handheld. 14 click 'esc' to leave this screen once the memory is empty.

Now you're ready to start the gps. 1) To start, make sure the job 'gage10' is active (it will say in the upper left corner: 'Job: GAGE10' 2) Click on 'Survey' 3) Click on 'FastStatic...' 4) Click on 'Start base receiver...' 5) Enter the point name on the 'start base' window. It will say 'point does not exist...' Just click 'OK'. 6) Set the antenna height to '0.00' 7) Measured to: 'bottom of antenna mount, 8) Survey will start. Click okay when it tells you to disconnect the comm cable. 9) After the gps has been found by the surveyor software again click 'instrument' 10) Click 'receiver files...' 11)Click 'import from receiver' 12) Make a note of the file name and modified date and time. 13) Hit 'esc' 14) Disconnect cable from ggps to handheld.


Use current props

Survey... Fast static survey Click start survey... That's it. Then R8 switches to a slow blink on gps led at this point

Look at battery (2 vs. 1 compatibility). External vs. Internal

Measure bumper to monument and also bottom of receiver to monument Need both measurements

Recommend doing a measurement at the start for setup and then also again at takedown.

At end: survey -> end survey
Battery

Need pigtail to charge survey hanheld.

At end just disconnect cable rather than shutting down the handheld the gps can potentially shutdown as well making the unit just sit there rather than doing the fast static survey.


Import files from receiver, pick ones we want... Hit import... Start. Now they're copied to controller (handheld)

After active sync is connected unit may buzz... Don't set up partnerahip, leave as guest. Then: mycomputer --> trimble data Data files are 4digits of serial number (1353) + time

1) Pull legs of tripod and extend to eye level. 2) Do an initial rough leveling of tripod 3) Put tribrach on tripod 4) Move tribrach leveling bits to middle (when indented ring is exposed) 5) Move tribrach until it is over monument 6) Level tribrach while keeping it over the monument. Site should be over the middle part of the monument. 7) Put R8 gps on hockey puck and mount to tribrach 8) Fire up the handheld 9) connect the TSCe to the R8 and delete any files on the R8 10) Set up a fast static survey. Be sure config fil 'gage10' is loaded. 11) When ready click 'survey' icon --> 'fast static...' --> 'start base receiver' 12) Punch in the station name 13) Set antenna height to zero 14) Start the survey 15) Disconnect from the gps 16) Reconnect... Wait till the gps has been communicated with and click on the 'instrument' icon. 17) Look at the receiver files and see the file on the instrument that is currently being logged to, make a note. 18) Pull the comm cable free of the r8 19) Plug in the external power (12v battery attached to lemo/alligator clip cable)

In addition, things to alway log to field book: Start date and time of survey Serial number of gps Draw a picture of the setting
