Cause : cannot be save comes when it is not possible to save the measurement results of a multiple trace on the memory card. A multiple trace is not started or is canceled.

- insert or remove the memory card.
- use a larger memory card.
- configure the trace with a longer trace time or use an endless trace.
- avoid saving parameters while the multiple trace is running. Saving parameters can Block writing measurement result files to the card, so that this alarm is output with alarm value 3
- check whether other functions are presently accessing measurement result files of the multiple trace.
