Claims (5)

1. Elektronische Waage mit einer Waagschale, mit einem Wägeaufnehmer, mit einer Justiergewichtsschaltung, mit einer digitalen Signalverarbeitungseinheit und mit einem Waagengehäuse, das den Wägeaufnehmer, die Justiergewichtsschaltung und die digitale Signalverarbeitungseinheit umschließt, dadurch gekennzeichnet, dass Hilfsmittel (26, 30, 31, 40, 41, 42, 50) vorhanden sind, die den Einfluß der verschiedenen Luftdichte oberhalb der Waagschale (3) und am Ort der Justiergewichtsschaltung auf das Justiergewicht (16) rechnerisch korrigieren.1.Electronic balance with a weighing pan, with a weighing sensor, with an adjustment weight circuit, with a digital signal processing unit and with a weighing housing, which encloses the weighing sensor, the adjustment weight circuit and the digital signal processing unit, characterized in that auxiliary means (26, 30, 31, 40 , 41, 42, 50) are present which mathematically correct the influence of the different air density above the weighing pan (3) and at the location of the adjustment weight circuit on the adjustment weight (16). 2. Elektronische Waage nach Anspruch 1, dadurch gekennzeichnet, dass die Hilfsmittel aus je einem Luftdichtesensor (30,31) in der Nähe der Waagschale (3) und in der Nähe der Justiergewichtsschaltung und aus einem Korrekturprogramm in der digitalen Signalverarbeitungseinheit (18) bestehen.2. Electronic balance according to claim 1, characterized in that the Aid from each airtight sensor (30,31) near the Weighing pan (3) and near the adjustment weight circuit and out of one Correction program in the digital signal processing unit (18) consist. 3. Elektronische Waage nach Anspruch 1, dadurch gekennzeichnet, dass die Hilfsmittel aus je einem Temperatursensor (40, 41) in der Nähe der Waagschale (3) und in der Nähe der Justiergewichtsschaltung und aus einem Korrekturprogramm in der digitalen Signalverarbeitungseinheit (18) bestehen.3. Electronic balance according to claim 1, characterized in that the Tools from one temperature sensor (40, 41) near the Weighing pan (3) and near the adjustment weight circuit and out of one Correction program in the digital signal processing unit (18) consist. 4. Elektronische Waage nach Anspruch 1, dadurch gekennzeichnet, dass die Hilfsmittel aus mindestens einem Temperatursensor (26) am Wägeaufnehmer und einem Korrekturprogramm in der digitalen Signalverarbeitungseinheit (18) bestehen, wobei der stationäre Unterschied in der Luftdichte oberhalb der Waagschale (3) und am Ort der Justiergewichtsschaltung in den Wert des Justiergewichtes (16) eingerechnet wird und der aktuelle Unterschied in der Luftdichte aus der zeitlichen Änderung des Messwertes des Temperatursensors (26) hergeleitet wird.4. Electronic balance according to claim 1, characterized in that the Tools from at least one temperature sensor (26) on Weighing sensor and a correction program in the digital Signal processing unit (18) exist, the stationary difference in the air density above the weighing pan (3) and at the location of the Adjustment weight circuit included in the value of the adjustment weight (16) and the current difference in air density from the temporal Change in the measured value of the temperature sensor (26) is derived. 5. Elektronische Waage nach einem der Ansprüche 1-4, dadurch gekennzeichnet, dass die Waagschale (3) allseitig von einem Windschutz (44...48) umgeben ist, der durch Verschieben mindestens einer Seitenscheibe (44, 45) geöffnet, bzw. geschlossen werden kann.5. Electronic balance according to one of claims 1-4, characterized characterized in that the weighing pan (3) on all sides by one Wind protection (44 ... 48) is surrounded by moving at least one Side window (44, 45) can be opened or closed.
