Since the middle of 2001 the Astro-Geodetic Obserwatory in Jozefoslaw has been equipped with new ET-26 LaCosteand Romberg gravimeter. This instrument is strictly dedicated to the Earth tides measurements. It has double lever system, double oven heating system and electrostating nulling which provide greater reliability and accuracy. This paper is aimed at describing the actions that had to be done before the recording started in the tidal laboratory in new building of the Jozefoslaw Observatory. These activities for instance were: electronic levels adjustment, instrumental phase lag determination as well as correctness of the voltmeter constant evaluation checking. The presentation contains the preliminary results of measurements at the tidal parameters (amplitude factors and phase shifts) derived from adjustment of first 5-months data. The concept of the synchronized tidal measurements made by two LC&R gravimeters (ET-26 and D-196) working in almost identical conditions in the same laboratory in Jozefoslaw is also presented.
