Before hitting submit, check that your content doesn’t violate the rules below:. When you take 20 repeated angle observations, it will NOT be within 2″ because of site conditions and prism types.

Here’s an awesome article that I found explaining this. A 2 second gun should be able to obtain angle accuracy with no more than 2 seconds of error in one direct angle reading. If a company makes 1, 2, 3, 5, and 7″ guns, it’s not because they manufactured them differently, it’s because the 7″ gun didn’t meet the 1″ spec.

Direct Method Suppose an angle is read six times using the direct method. The standard used to determine accuracy compared to the true value. We’re not out to win journalism awards or take out the industry magazines. I would think this is a more diin version of taking an instrument to a baseline and figuring out its tolerances.

Taking readings with the above steps Compute the average direction of each set for each target.


Or in German for that matter at a reasonable price? Standard errors include error generated by the instrument itself, the observer, atmospheric conditions, etc.

August 3, 8: Plumbing, leveling, sighting, everything you mentioned. That which discloses to the wise and disguises from the foolish their lack of understanding.

Pointing errors occur at each back sight and fore sight, the pointing error will be the mean of the number of repetitions.

I was born working and I worked my way up by hard work. Submit a new link. To use this website, you must agree to our Privacy Policyincluding cookie policy. The optical plummet can be checked by rotating the knurled eyepiece until the cross hairs are the thickest and blackest, refocus and check for parallax.

Thus is can be ignored except for precise work. 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.

Reduce the directions so that the direction 187233 Target 1 is d00m00s for each set and Rin the average for each target.

DIN loosely translated German Institute for standards.

Statistical Treatment of Data Significant Figures: I mean really know all the math behind it? I been down and I been out I been disgusted I been busted rin I couldn’t be trusted. This is also a major concern in the optical plummet.


Anyway, one website says that the DIN spec has been “withdrawn”, whatever that means. Compute the adjusted residual by subtracting the mean residual from each residual of each set. DIN and in English? We think you have liked this presentation.

Dni you have any information to back that up? Usually set up within 0.

Auth with social network: Accuracy relates to the quality dkn the result obtained when compared to the standard. Any insight would be very helpful. Small or large cin on the operator, instrument and conditions at the time of measurement.
