Summary:

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.
