The calibration of coded levelling rods and the systemic calibration of digital levelling instruments. The calibration on linear comparative baseline in a terrain ¨C the elaboration of measured data. The testing of universal measuring instruments in laboratory conditions - specific problems in testing of instruments with the passive reflection.
