Summary:

To verify the precision of measurements made with a precise electronic total
station Leica TC 2003, test measurements consisting of 36-fold measurement of
distances and horizontal angles were taken, measurements were made in two telescope
positions.
To examine the compatibility of the distribution of experimental errors with
the theoretical distribution N (0;1), which would indicate a proper working of the
tested 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 measurements
with the tested instrument.
