The paper presents the problem of determining the accuracy usable of geo-detic Instruments. The results of test measurements will be evaluated using tests of mathematical statistics by the statistical Abeb's test and the Shapiro - Wilk test. Will discuss the theoretical basis for conformance testing and arę given ways of their practical application.The study concludes that the tested instruments meet the conditions of both statistical tests and thus arę suitable for making measurements in engineering geodesy .

In order to verify that the angular measurements performed with a precise theodolite "WILD T 2002" are burdened with systematic errors, numerous of an-gular measurements were performed in the test grid composed of three adjacent triangles, located near the Department of Environmental Engineering and Geodesy, University of Agriculture in Cracow.The occurrence of systematic errors may indicates that the distribution of measurement errors is not normal. This would force a different way to compensate the observations than the least squares method. Measurements made 35 times, were statistically analyzed using the Shapiro - Wilk test.To control the results of test, additional statatistics measurements were performed using the methods specified by: 1. Kołmogorow's - statistics D and D'2. Kuiper's - statistics V and V1.Performed analysis allows to draw conclusions regarding the suitability of the test instrument for angular measurements.

In order to verify that measurements made with a digital leveler "WILD NA 3000" are burdened with errors, distorting the results of these observations, nu-merous measurements of height differences between points of a leveling net set up in the Department of Environment and Geodesy of the University of Agriculture in Cracow were performedMeasurements were made on a network of three closed leveling mesh, assessing of height differences in those leveling mesh 35-times. To detect possible anomalies in the measurement, a statistical compatibility tests of Kolmogorov - Liliefors was used, checking the hypothesis Ho of normal distribution of measurement errors. To verify and confirm the results coming from concerned test, additional test were launched using the statistics: Cramer - von Mises: W2 and W12Watson: U2 and U12 Performed analysis gives overview on measurements quality with use of tested instrument.
