Data output

V. d. from AVM achieve to different gauges of stress, indicators and oscillographs. For the measurements and registering the slowly changing stresses the digital voltmeter (see digital instrument) uses with the digit-printing machine or the perforating prefix. For the record on the paper tape of those changing in the time one or several variables, represented in the form of stress, use electronic chart recorders. Indicator with the cathode-ray tube ensures the visual observation of one or several values in the function of time or in the function of other variables, the measurement of the instantaneous values of the observed values and their marking with time markers. Indicator, as a rule, is supplied with photo attachment. Loop oscillographs convert the investigated signals into the displacement of light ray over the sensitized paper; oscillograph ensures registration ok. 10 parameters. However, the complexity of working oscillograms and their relatively low accuracy decrease recording efficiency.

V. d. from TSVM - DIGITAL COMPUTER achieve into the memory OF COMPUTER(S) (into vnesh. memory unit - tape, drum, disks, etc.), to perforats. of tape, maps, to the alphanumeric printers, on CRT with the sign indication (see charactron, typotron), to the graph plotter and so forth speed v. d. on the magnetic tape it composes tens of thousands of signs per second, to the punched cards and the punched tape to it is several of thousand signs per minute. Press systems with the formation of signs on the the electro-static are developed. and magnetic surfaces. In similar devices the charged or magnetized microparticles of coating under the action of elec. or magnetic field are concentrated into opredel. the points of surface; in this case clear imprint is obtained. Depending on the method of the formation of signs the speed of electrostat. press comprises from several thousand to several ten thousand signs per second. One of the most visual methods is v. d. to the charactron and taypotrop; speed in this case reaches several ten thousand signs per second. Image on the screen can be photographed.

With the joint operation AVM and TSVM - DIGITAL COMPUTER the exchange of information occurs through the appropriate converter of the idea of values.
