And by probably, I mean definitely.
No self promotion or direct linking to items for sale. August 3, 9: So, for a 2″ Din spec instrument: We’ve established a quality community of surveying friends, mentors and enthusiasts, where we can all hang out, 81723 and have some fun sharing our experiences and helping each other.
Parallax occurs when the focal point of the eyepiece does not coincide with the plane of the cross hairs. August 3, 6: Direct Method Suppose an angle is read six idn using the direct method.
Forum contains no unread posts Forum contains unread posts Mark all read. Accuracy relates to the quality of the result obtained when compared to the standard. How much is determined by several factors.

Reduce the directions so that the direction to Target 1 is d00m00s for each set and Calculate the average for each target. Hi all I am trying to understand instrument standard deviations for precision.
We’re not out to win journalism awards or take out the industry magazines. Does anyone know how to obtain these in English? Small or large depending on the operator, instrument and conditions at the time of measurement. Slowly move the head back and forth, djn an inch from the eyepiece, while watching the relationship of the object to the dib hairs.

Conrad posted his results of an investigation of the Leica circle reading system and discovered that the circle reading system in effect adds a pseudo-random error to the direction reading so that a nearly perfectly graduated circle appears to give directions with random-appearing errors with an s. I want the full DIN standard to see if there’s any other useful stuff that I should know about these precisions.
Add value or move along. I ain’t ever got no where, but I got there by hard work. You ensure through manufacturing and testing that an instrument meets a specific result. Log in or sign up in seconds. In other words, “your mileage may vary”. Compute the residual for each set and each target and the mean residual. I mean that the DIN number you come up with for that instrument is specific to that one instrument. In the real world there will be many other sources of error in the operation.
To check for parallax in the telescope, focus on some well-defined distant object. Kent, I guess you forget that you are an anomaly. A survey or map deemed sufficiently near the ideal or true value to be held constant for the control of dependent operations.
If you look at the title of DIN its: August 3, Compute the adjusted residual by subtracting the mean residual from each residual of each set. Or, in the case of Leica, using a circle with known periodic errors in its graduations that is either partially or entirely removed by the reading system software, depending upon the instrument accuracy spec.

I hope that makes sense.
