Claims (5)

1. Vorrichtung zur mechanischen Nullpunkteinstellung von photometrisch arbeitenden Meßgeräten, insbesondere photometrisch arbeitenden mit Meßlicht- und Referenzlichtstrahlengang (8) ausgerüsteten Zwei- Strahl-Meßgeräten, die aus einer Lichtquelle (1), einem teildurchlässigen Spiegel (2), einer Meßküvette (3), einem Photosensor für Referenzlicht mit Signalaufbereitung (4) und einem Photosensor für Meßlicht mit Signalaufbereitung besteht, dadurch gekennzeichnet, daß eine einstellbare Mechanik für Meßlichtsteuerung (6) im Meßlichtstrahlengang (8) und eine einstellbare Mechanik für Referenzlichtsteuerung (7) im Referenzlichtstrahlengang (8) selbstsichernd oder sicherbar gegen Verschieben oder Verdrehen zur Nullpunkteinstellung angeordnet sind.1. Device for the mechanical zero point adjustment of photometrically working measuring devices, in particular photometrically working with measuring light and reference light beam path ( 8 ) equipped two-beam measuring devices, which consist of a light source ( 1 ), a partially transparent mirror ( 2 ), a measuring cell ( 3 ), There is a photosensor for reference light with signal conditioning ( 4 ) and a photosensor for measuring light with signal conditioning, characterized in that an adjustable mechanism for measuring light control ( 6 ) in the measuring light beam path ( 8 ) and an adjustable mechanism for reference light control ( 7 ) in the reference light beam path ( 8 ) are self-locking or are arranged to be secured against displacement or rotation for the zero point adjustment. 2. Vorrichtung nach Schutzanspruch 1, dadurch gekennzeichnet, daß die einstellbare mechanische Vorrichtung für die Meßlichtsteuerung (6) und die Mechanik für die Referenzlichtsteuerung (7) aus einer Schraube, einem Schieber oder einem Stift, selbstsichernd oder sicherbar gegen Verdrehen und/oder Verschieben, besteht, die je nach Bedarf entweder in den Referenz- oder den Meßlichtstrahlengang soweit einbringbar sind, bis das gewünschte Verhältnis von Meß- zu Referenzlicht, das heißt der Nullpunkt, erreicht ist. 2. Device according to protection claim 1, characterized in that the adjustable mechanical device for the measuring light control ( 6 ) and the mechanism for the reference light control ( 7 ) from a screw, a slide or a pin, self-locking or lockable against rotation and / or displacement, exists, which can be inserted into the reference or the measurement light beam path as required until the desired ratio of measurement to reference light, that is to say the zero point, is reached. 3. Vorrichtung nach Schutzanspruch 1 oder 2, dadurch gekennzeichnet, daß die Mechanik für die Meßlichtsteuerung (6) und/oder die Mechanik für Referenzlichtsteuerung (7) handbedienbar oder elektromechanisch betätigbar bzw. einstellbar ausgeführt ist.3. Device according to protection claim 1 or 2, characterized in that the mechanism for the measuring light control ( 6 ) and / or the mechanism for the reference light control ( 7 ) is designed to be manually operated or electromechanically actuated or adjustable. 4. Vorrichtung nach Schutzanspruch 1 oder 2, dadurch gekennzeichnet, daß die Mechanik für Meßlichtsteuerung (6) und/oder die Mechanik für Referenzlichtsteuerung (7) durch einen Elektro- oder Schrittschaltmotor mit mechanischer Ankopplung die Vorrichtung zur Nullpunkteinstellung bildet.4. Device according to protection claim 1 or 2, characterized in that the mechanism for measuring light control ( 6 ) and / or the mechanism for reference light control ( 7 ) by an electric or stepping motor with mechanical coupling forms the device for zero adjustment. 5. Vorrichtung nach einem der Schutzansprüche 1 bis 4, dadurch gekennzeichnet, daß die Meßküvette (3) auswechselbar und ohne Neukalibrierung des Meßgerätes wiedereinsetzbar ausgebildet und/oder angeordnet ist.5. Device according to one of the claims 1 to 4, characterized in that the measuring cuvette ( 3 ) is designed to be replaceable and reinsertable without recalibration of the measuring device.
