Field Collimations with Trimble S Series Robotic Total Stations
Extreme temperature changes so let the instrument acclimate
Do not collimate on windy days and let angles settle before collimation
Manufacturer’s recommended minimum annualservice calibrations
• Field calibration
• Before the start of large projects
• AT LEAST once every quarter
• Tracker Collimation once per month
• Large temperature changes
Checking the Electronic Level
• Level the instrument
• Note the Trunnion and Sighting values
• Turn the instrument about 180 degrees
Checking the Electronic Level
Data should be the same but with different signs
With the instrument connected to
the controller select the
Instrument tab
Next select the Adjust tab
First we will go through the Compensator
Calibration. Make sure it is selected and
hit next
Make sure the instrument is on a
stable setup and level. Select the
Next tab.
The instrument will turn and run it’s
calibration.
The process will take approximately
a minute to complete. If the
message shows Calibration
complete tab OK.
How to check manual aiming accuracy in single face measurement
• Step 1: aim towards a target
Set up the instrument on a stable surface and
follow the prompts to complete the test.
Current adjustment values appear for each test
(Horizontal collimation, Vertical collimation, and
Trunnion axis tilt). Press the keys lightly to avoid
bumping the instrument.
Aim at the target and take the first
measurement.
Turn the instrument away and then re-aim.
Take the second measurement.
Note - Do not use Autolock during Collimation or
Trunnion axis tilt tests.
Position the instrument as follows:
Collimation - at least 100 m from the target.
Collimation - less than 4°30’ (5 gon) from the
horizontal plane.
Check Collimation Results
Autolock collimation
This option is available only for instruments
with Autolock, and should be performed
after the HA VA Collimation adjustment has
been completed.
Set up the instrument on a stable surface
and follow the prompts. Press the keys
lightly to avoid bumping the instrument.
Ensure that there are no obstructions
between the instrument and the target,
which should be at least 100 m apart.
