How to Auto Level Calibration

Proper calibrations are essential if you want to receive accurate readings, and when it comes to the use of the auto level, you definitely want to receive accurate readings.

Failing to calibrate your auto level to account for precise variations and fluctuations in your particular application of the tool can result in the production of completely fictitious and utterly useless information.

This guide will help teach you how to prevent such mistakes.

Improper Measurements are Useless

Nobody wants to spend hours of their day collecting measurements only to discover that those measurements have no factual bearing on reality nor any potential use. If you’re going to waste hours of your time, why waste it doing something so taxing as taking auto level measurements?

How to Calibrate Your Auto Level

The first step involves loosening the protective cover on the top of the auto level. Next, you’ll want to align the auto level in between two markers roughly 60 meters apart. Take the reading of the backsite and the foresite and account for collimation.

Move the auto level closer to the foresite so that the distance between the foresite is equal to one tenth of the distance between the backsite and the foresite. Write down that number.

Once this is done, tighten the screws on the protective cover, move back to the center, and take your readings. They will now be much more accurate than before.


Knowing proper calibration techniques can save you countless hours of frustration when it comes to surveying new locations, because a poorly calibrated auto level isn’t much good for anything.
