FAQ
How often should an instrument be calibrated?
Check it periodically, after any drop, knock or long transport, and before high-accuracy projects. Heat and dust increase the need.
What are the signs it needs calibration?
Readings that change on re-measurement, traverses that do not close, face-left/face-right differences or compensator errors.
Do you give a report after calibration?
Yes. We hand over a report of the checks we performed and their results.
Do you service all brands?
We work with common brands such as Leica, Topcon, Sokkia, Trimble, South and Hi-Target. Send the model to confirm.
