Field Support
Survey Equipment Maintenance
Calibration schedules, cleaning procedures, battery care, warranty information, and guidance on when to service versus replace — for Topcon, Leica, Spectra Precision, Bosch, and SitePro laser equipment.
Maintenance How-To Guides
Field procedures for keeping instruments accurate and field-ready.
How to Clean and Maintain a Total Station
Step-by-step field cleaning procedure: optics, tribrach, display, and EDM window. Covers storage, transport, and annual service intervals.
How to Extend Battery Life on Survey Equipment
Charging best practices, storage temperatures, discharge cycles, and battery replacement indicators for NiMH and Li-ion packs.
How to Calibrate a Rotary Laser Level
Two-peg and bucket-of-water calibration methods. Covers when calibration is required and how to document results for crew records.
How to Perform a Two-Peg Test
The standard field test for verifying instrument collimation. Required before critical layout work and after any drop or impact.
How to Check the Level Vial on a Survey Instrument
Inspect and adjust the circular bubble and plate vial on optical levels, total stations, and GNSS poles.
Calibration Due Date Tracking
Most manufacturers recommend annual calibration for total stations, GNSS systems, and pipe lasers used in production work. Rotary lasers should be checked with a two-peg test every 90 days or after any drop.
Gradelog is a cloud-based calibration and service tracking platform that logs instrument serial numbers, last calibration dates, due dates, and service history across your entire fleet.
