In order to check if measurements of vertical angles and displacementsmade by electronic total station Nikon NPL-352 are not burdened with systematicerrors, test measurements were performed.Measurements depended on that vertical angles and elevations to selectedsharp visible, high located points. Vertical angles were measured in two telescopepositions picking 36 measurements.Elevations were measured in one telescope position, also in number of 36.For the study were calculated coefficients:1) flattening „e"2) asymmetry „S"and their medium errors me i mSFor the control of these results, the second independent Anderson - Darlingtest was made.Conclusion drawn from the study confirms the accuracy of measurements. ...
To verify the precision of measurements made with a precise electronic totalstation Leica TC 2003, test measurements consisting of 36-fold measurement ofdistances and horizontal angles were taken, measurements were made in two telescopepositions.To examine the compatibility of the distribution of experimental errors withthe theoretical distribution N (0;1), which would indicate a proper working of thetested equipment, two methods of statistical surveys were used:1. calculating the distribution parameters: a) flattening „ e"b) assymetry „S"and their average errors,2. Anderson-Darling statistical test of compatibility .The study allowed to conclude correctness of results obtained from measurementswith the tested instrument. ...
