The micrometer is used for measuring star coordinates and B,V,R magnitudes. Six inclined slits (7.8″wide) scan the images. For the relative scanning velocity of 30″s one obtains 36 image profiles in 30 s. Moments of star transits through the centres of slits are determined by the median method in the real-time mode. Test observations have shown that random errors are 0.30 - 0.33″and 0.12m for coordinate and V magnitude measurements of stars down to 9.5m. The influence of major instrumental errors and atmospheric instability on the precision of observations is analysed. It is shown that the micrometer allows to locate a star position in its own coordinate system with an accuracy of 0.04 - 0.07″
