Die Verfahrensschrittr machen es möglich, das vorgewählte Testinstrument anzusteuern und zur Simulation von Betriebszuständen in br stimmter Weise zum Ausschlag zu bringen, z. B. von einom Endpunkt auf einen Maximumausschlag kontinuierlich zu durchfahren, oder Fixpunkte zur Anzeige zu bringen. Es versteht sich, daß auch anderweitige, beliebige Ausschläge bei Anm Testinstrument ansteuerbar sind. Bei einer Vorrichtunc /or Durchführunq des Verfahrens ist die Kombination eir.orAccording to the invention it is provided for this purpose that a test program adapted to the test instrument is selected by means of a coding switch on a program preselection unit and that a sequence control unit is given a signal to a micropro7P? For and a memory and that predetermined test pulses are generated for the test instrument via an output . ■ the unit is given to the test instrument and indicated by it, or can be passed through. The procedural steps make it possible to control the preselected test instrument and to bring it to a rash in a certain way to simulate operating conditions, e.g. B. to run continuously from an end point to a maximum deflection, or to bring fixed points to the display. It goes without saying that otherwise, any rashes can be controlled in Note test instrument. In the case of a device or implementation of the procedure, the combination of a

Zum Testen eines KombinationsInstrumentes wird wie folgt vorgegangen. Zumachst wird mittels des Codierschalters 2 in der Typenvorwahleinheit 1 der Testinstrumententyp vorgewählt. Danach erfolgt Starten durch Drücken des EinAusschalters 5. Das in der AblaufSteuereinheit 4 gewonnene Signal wird dem Mikroprozessor 8 und von dort dem Speicher 9 auf bestimmter Stelle zugeführt. Sodann erfolgt aufgrund des gespeicherten Programms Ansteuerung des Testinstruments zu vorbestimmten Anschlägen, z. B. kontinuierlich von Null auf Maximum (Tankkontrollanzeige), oder mehrere Fixpunkte, die z. B. Geschwindigkeitsanzeigen betreffen, gegebenenfalls mit nachfolgendem kontinuierlichen Durchfahren von Null bis Maximum, um ein etwaiges Verhaken des Zeigers zu prüfen.To test a combination instrument, proceed as follows. First of all, the type of test instrument is preselected by means of the coding switch 2 in the type preselection unit 1. Then start by pressing the on / off switch 5. The signal obtained in the sequence control unit 4 is fed to the microprocessor 8 and from there to the memory 9 at a specific point. Then , on the basis of the stored program, the test instrument is controlled to predetermined stops, e.g. B. continuously from zero to maximum (tank control display), or several fixed points that z. B. concern speed displays, possibly with subsequent continuous traversing from zero to maximum to check whether the pointer gets stuck.
Die Verfahrensschritte und die Vorrichtung sind auch für den Serviceeinsatz in Werkstätten verwendbar.The method steps and the device can also be used for service use in workshops .
