How to use Forums
Our forums on Land Surveyors United are here to be used as much for finding help with problems in the field as the are for you to express your opinions on anything that has to do with land surveying in general. Feel free to share anything that is on your mind, as long as it isn't meant to damage another member's reputation. Please keep it clean and help insure that everyone has the opportunity to enjoy the benefits of being part of a community that grows together.
We are committed to allowing freedom of expression for all of our members, and that includes maintaining a safe space for people with opposing views to express themselves. We get posts from all over the country and even the globe, so needless to say, people come with different viewpoints on lad surveying practices and processes. We see this diversity and variety as a real strength-- dialogue and debate are an integral part of the educational process, as well as an important tool in exploring different sides of complex issues.

Community Hubs inside the community have their own forum for asking specific questions to other surveyors, by location, equipment type, etc.

Are you referring to the standard deviation of the instrument after calibrating your instrument? Does your county or state have a calibration range where you can calibrate your instrument. From there you will then be able to obtain the true correction and the standard deviation of your instrument.Ā

is this correct?
