Now, if a surveyor is using poorly 17823 targets in poor seeing condititions, sure, all bets are off. Each source produce a small amount of random error.

I mean that the DIN number you come up with for that instrument is specific to that one instrument. I ain’t ever got no where, but I got there by hard work.

Kent, I guess you forget that you are an anomaly. True Location Dependent on quality of instrument State of adjustment of optical plummet Skill of observer Can be compensating Error is maximized when the individual setup is on the angle bisector. I been down and I been out I been disgusted I been busted and I couldn’t be trusted.


Wow 118723 is awesome thanks!

Then again, at that point you’re really splitting hairs, but I’d be curious as to how different the numbers are. What is the estimated error in the angle due to pointing and reading? Compute the standard error or the standard deviation for session 1. Error is always present in all measurements.

Pointing errors occur at each back sight and fore sight, the pointing error will be the mean of the number of repetitions. Parallax occurs when the focal point of the eyepiece does not coincide with the plane of the cross hairs.

I have the 12th edition at sin. Recheck the instrument level If the instrument has moved, check the angle just measured. Log in or sign up in seconds. Welcome to Reddit, the front page of the internet.

In other words the difference in price buys the exact same instrument, but with a few more lines of code active in the internal software. So, for a 2″ Din spec instrument: You ensure through manufacturing and testing that an instrument meets a specific result. Forums Recent Posts Login Register. Second of all, while it may well be that instruments with dual-axis compensators give angles measured on only one face that are free of collimation errors, it is an open question whether the graduation of the circle places strict limits on the improvement 1873 the s.
