ELECTRONIC LABORATORY METERING SYSTEM FOR LIQUIDS AND METHOD FOR OPERATING AN ELECTRONIC LABORATORY METERING SYSTEM FOR LIQUIDS

摘要

The invention relates to an electronic laboratory metering system for liquids, comprising at least one electrical hand-held metering device (2) which has at least one operation sensor unit (5) that detects operation of the hand-held metering device (2) and generates operating data in this respect and in particular stores same in a storage apparatus (6) of the hand-held metering device (2), wherein: the hand-held metering device (2) has an interface module (7), by means of which the hand-held metering device (2), in particular for transferring the operating data, can be connected via a data connection to an external network access apparatus (4); the network access apparatus (4) can be data-connected to an external data processing system (3); the data processing system (3) can be data-connected to at least one context parameter sensor unit (8), which detects operation of the hand-held metering device (2) at least indirectly and/or detects operating environment conditions of the hand-held metering device (2) and generates context parameter data therefrom; the metering system (1), in particular the data processing system (3), has a comparison unit (9), which is designed at least to compare operating data from the operation sensor unit (5) with target operating data and/or to compare context parameter data from the context parameter sensor unit (8) with target target context parameter data and to generate a comparison result, in particular a deviation of the data, identified during the comparison, from the target data; the metering system (1) comprises a documentation unit (10), which is designed to generate and store log data records concerning the operation of the at least one hand-held metering device (2), in particular comprising at least the operating data and/or the context parameter data; the documentation unit (10) is connected to the comparison unit (9) in such a manner that the comparison results from the comparison unit (9) can be transmitted to the documentation unit (10) and the documentation unit (10) is designed to store the comparison results as part of the log data records, in particular so as to be assigned to the relevant operating data and/or context parameter data, in particular to add to same after the operation of the hand-held metering device (2) has ended.
