1. A data-recording device for a measurement device (2),
wherein the measurement device (2) contains measurement device electronics (3) having an internal data bus and a first data interface connector (4), wherein the data-recording device includes at least one storage element (5), at least one processing unit (6) linked with the storage element (5) and a second data connector interface (7), wherein the data-recording device can be linked with the measuring device by mechanically connecting together the first and second interface connectors so that data can be exchanged between the measurement device (2) and the data-recording device, wherein the data-recording device can read-only access the internal data bus of the measurement device (2) without functional influence via said second data interface connector (7)—bus observation—by tapping the internal data bus of the measurement device (2) in order to observe the data on said bus without functionally influencing the internal operation of the measurement device (2) or the measurement device electronics (3) via said second data interface connector (7), and wherein the read-only access of the internal bus of the measurement device does not initiate services, by the data-recording device, for data retrieval in the measurement device electronics, wherein the data-recording device is supplied with required electrical power from the measurement device. |
