What is the difference between "Retrieve raw data" and "Read out raw data"?
For "Read out raw data" it is possible to specify the percentage of measured data to be read out or the time range of measured data.
For "Retrieve raw data", only measured data that has not been read out previously can be read out.
Furthermore, the memory alarm of the device is not influenced by "Read out raw data". "Retrieve raw data", however, influences the memory alarm. A possibly pending alarm is deleted once the data is retrieved successfully.
