1. An electronic laboratory metering system (1) for liquids, comprising:
at least one electrical handheld metering device (2) having at least one operation sensor unit (5) detecting the operation of the handheld metering device (2) and generating corresponding operating data and, the handheld metering device (2) having an interface module (7) by means of which the handheld metering device (2) can be connected to an external network access device (4) via a data connection, the network access device (4) being data-connectable to an external data processing system (3), the data processing system (3) being data-connectable to at least one context parameter sensor unit (8) (a) at least indirectly detecting the operation of the handheld metering device (2) and/or (b) detecting environmental operating conditions of the handheld metering device (2), and generating context parameter data therefrom, the data processing system (3) having a comparison unit (9, 29) configured at least (a) to compare operating data of the operation sensor unit (5) with target operating data and/or (b) to compare context parameter data of the at least one context parameter sensor unit (8) with target context parameter data, and to generate a comparison result,
wherein
the metering system (1) comprises a documentation unit (10) which is configured to generate and to store protocol data sets relating to the operation of the at least one handheld metering device (2), the documentation unit (10) being connected to the comparison unit (9, 29) in such a manner that the comparison results of the comparison unit (9, 29) can be transmitted to the documentation unit (10) and the documentation unit (10) is configured to store the comparison results as part of the protocol data sets.
