PiCUS TMSO Manual
20
Each TMSO.IM has a small internal memory that allows the recording of a maximum number
of pitch events (event memory locations). The default setting is 10 events (see also
12.3.1.1Max. Number of Events per Measuring Cycle
) with a recording length of 10 seconds
before and 10 seconds after the maximum slope value (see also
processing Time for Event Recording
). These settings should only be changed by experienced
users!
The following diagram illustrates the recording window:
If a TMSO.IM now detects an inclination event, it will record the required curve for a total of 20
seconds and store it in one of its event memory locations. If all memory locations are already
occupied, it will replace the event with the smallest amplitude with the new one. Thus, at the
end of the measurement cycle, each TMSO.IM will have the up to 10 strongest inclination
events of this period in its memory.
The following sketch shows an example of the measuring process and the event selection of
a measuring cycle:
Once the measurement cycle is complete, all TMSO.IMs will stop their measurement
operations and activate their TMSO Radio, as well as the TMSO.CU.
