Seiler service calibrates your optical instrument at least once a year- right? Calibrations are a good practiceย but instrument collimations should also be done regularly as wellย and reporting them for historical purposes is available. Using a custom survey XML Style sheet (XSL), users can generate a report of all collimations performed via the data collector in a particular job. This report presents the instrument collimation details that have been recorded in the job file. It will present each unique set of collimation details so that, if the instrument collimation has been adjusted during the course of the job, the collimation details before and after the adjustment will be reported. Similarly, if different instruments have been used in a job then the collimation details for each instrument will be reported.
Customย XML style sheets (XSL)ย may be used to generate reports directly on a data collector orย a user can useย the style sheetsย in theย ASCII file generator utility or the Job report generator in Trimble Business Center on a laptop or desktop PC.
Step 1: Download the Instrument Collimation Reportย XSL style sheet from the Trimble website. The downloaded zip file contains a jpg picture of what the report looks like and the actual XSL style sheet.

Step 2: Save XSL
- Save to the Trimble Data/System File folder on your Trimble Access data collector
- Save toย the Trimble Data Folder on your Survey Controller data collector
- Save to aย local drive location on your computer if using ASCII file generator or Job report generator
Step 3: Perform the Instrument collimation and apply
EDITED FROM TRIMBLE USERS GUIDE:
In Trimble Access > General Survey, select Instrument >ย Adjustย
Noteย – Instrumentย >ย Adjust is not available during a survey. End the current setup via Measure > End conventional survey before attempting to perform an instrument adjustment.
Perform HA VA Collimation and Horizontal tilt axis test
Set up the instrument on a stable surface and follow the prompts to complete the test. Current collimation values are displayed in each test (Horizontal collimation/Vertical collimation and Horizontal tilt axis).ย To take a measurement, aim at the target. Take the first measurement, turn the instrument away, and then re-aim. Take the second measurement. When turning the instrument away from the target, turn it away in different directions each time to insure good sightings.
Noteย – Do not use Autolock during Collimation or Horizontal tilt axis tests.
Testย the instrument as follows:
- For both collimation tests – Instrument should be at least 100 m (~328 ft) from the target.
- HA VA collimation – should be on a horizontal plane- target should be less than 5ยฐ higher or lower than the instrument
- HZ Tilt test – target should be at least 14ยฐ above or belowย the horizontal plane.
You must take a minimum of one observation on each face. Seiler recommends three or more.
Final collimation values must be within 0.02 gon (= 0ยฐ01’05”) of standard values. If not, adjust the instrument mechanically. Send toย a Seiler Service department.
Step 4: Generate the collimation report on the data collector
-
- From the main General Survey menu select Jobs – Import / Export – Export custom format
- Set the file format to Instrument Collimation Report
- Fill in a report File name, select the proper folder and tap Accept
- Message will appearย Transferย complete.ย Tap OK
- If the โView created file was checked, the report will pop up for viewing
- An HTM report with all collimationsย for this job will be generated in the specified folder and may be downloaded via Mobile device center to a computer or via AccessSync with a SW valid warranty.
To use the ASCII file generator or Job report generator in TBC contact your Seiler sales rep for the custom export style sheet support note instructions.
Note:ย The variousย Adjustment testsย may also be performed via the onboard face 2 displayย of S-series instruments that have a face 2 display. The results from this process of testingย will not be reported as part of this XSL style sheet report as they are not stored in any job file.
