Methods Of Improving The Measure And Display Precision In An Arrangement For Interrogating And Representing Several Values To Be Measured Abstract of the Disclosure This invention provides a method of improving the measure and dis- play precision in an arrangement for interrogatinq several values to be measured which are picked up by input/output devices or service proces- sors of a computer system, and generally by discrete and discretely ad- dressable functional units, where the individual functional units are connected to an address channel and predetermined addresses are associ- ated thereto, and where furthermore the individual functional units are connected to a measure data channel via which, after addressing and switchinq, data are transferrable to a central location, and where for the time representation of these measure values on a display device, all desired measure positions of the one service processor selected by means of the selected address being switched simultaneously via the central measure data channel with a central measuring processor, a trigger signal supplied by the selected service processor and applied on a measure data channel line is selectable for synchronization, this trigger signal fur- thermore causing the central measuring processor to start interrogating in predetermined intervals all measure data signals on the measure data channel simultaneously, and where finally the momentary measure values in that interrogation are stored in a storage and displayed in parallel and simultaneously in different lines on the alphanumeric screen used as display device with column and line representation, the screen having a storage where all characters displayed on the screen can be stored and used again and again for display, and where each column of the screen has an associated interrogation pulse, characterized in that upon each second newly triggered cycle the interrogation pulses, relative to the interrogation pulses of the preceding cycle, are staggered as a whole with respect to time, said time staggering being relatively small regard- ing the spacing of two interrogation pulses. - 1 -
