Rudolf Radnai: Measuring with logic analyzers (4). Practical advices It is essential to know the tasks and functioning of controlling and error correcting units that can be found in up-to-date microcomputers. In the article the function­ing and application of these units is described and il­lustrated by examples. Dr. Gyula Lukács: Repeatability and accuracy of stereo­scopic measurements (solution of the MOMCOLOR 1000 colorimeter) There is no uniform practice to define measuring uncertainty and measuring accuracy when the result of the measurement is given by three variables and rep­resented by a point in the space. The two metrological characteristics are not appropriately given for the dif­ferent types of instruments. The new automatic tri­stimulus instrument made by the Hungarian Optical Works (MOM) is characterized by the new colorimetric repeatability, colorimetric accuracy and with the instru­ment's average accuracy. 3
