Lab activity

The Laboratory engages inthe measurement and calibration of a part of electric quanties (voltage, current, resistance, power), electric measurement of non-electric quantities (deformation,
displacement, force, pressure, temperature, sound and noise, vibrations), in static and dynamic area and estimating the measurement uncertainty. Useof Labview program package enables the development of virtual measurement systems with system data acquisition and calibration of measurement chain and virtual instruments. The Laboratory has been developing the technologies ofprogram design and 3D objects production.
