Multiple trace
A multiple trace consists of single, completed, consecutive traces. Using multiple tracing on
a card, it is possible to cyclically record (a specific number) traces with the same trace
configuration (number of channels, sample depth, recording cycle,..), and to save these
traces persistently on the drive memory card.
The "Endless trace", "Single trace" and "Multiple trace" functions cannot be used
simultaneously. With a correspondingly incorrect configuration, alarm "A02097" is output.
However, a multiple trace with a cycle of 1 is nothing more than a single trace with saved
measurement results.
NOTICE
Shorter service life of memory cards as a result of multiple traces.
The service life of the cards can be shortened by the multiple traces because the memory
media is subject to wear as a result of the write access operations from a technical point of
view.
Note
The performance of the complete system can be negatively influenced by a continuous
multiple trace.
Requirement
A multiple trace is only possible if the memory card is plugged in and not blocked. In this
case, alarm "A02098 MTrace: Cannot be saved" is output with alarm value "1".
Activating a multiple trace
Note
The multiple trace can be activated or set separately for each trace recorder.
