Electronic device for recording, storing and processing measured data, particularly a data logger
First Claim
1. Data logger comprising interconnected function blocks located within a common housing, wherein the function blocks include:
- at least one analog/digital converter for conversion of measurement signals into digital input data;
a memory unit for recording of digital data and of digitized event data;
a timer;
a processor unit for processing of data;
a power supply source; and
input and output interfaces for measurement signals or digital data and event data, wherein the processor unit is configured to convert digital input data and time data into a data format which is compatible with standardized software such that processed data can be displayed using the standardized software in tabular and/or graphic form on an output device, and wherein the digital input data and time data as well as the event data are embedded by the processor unit as protected raw data into the data format such that they can be read and processed only with hardware-specific evaluation software,wherein format conversion and preparation and the embedding of the digital input data and time data as well as the event data into a protected region of the data format is activated by the processor unit only when recorded data are read out.

Abstract
A data logger is disclosed wherein a common housing includes different function blocks which are connected to one another. These function blocks include at least one analog/digital converter for conversion of measurement signals into digital input data, a memory unit for recording of digital data and of digitized event data, a timer, a processor unit for processing of data, a power supply source and input and output interfaces for measurement signals or digital data and event data. The processor unit is configured for conversion of digital input data and time data into a format which is compatible with standardized software (e.g., freely available) and which makes it possible to display the processed data using standardized software in tabular and/or graphic form on an output device. The processor unit can be configured to embed the digital input data and time data as well as the event data as protected raw data into the generated data format such that they can be read and processed only with hardware-specific evaluation software.
