Function DescriptionSelectionCode
Trigger delay The trigger delay defines when to begin with the saving of the measured values with
regard to the trigger time.
C0737
-100.0 % ... 0 %
• Negative trigger delay (pre-triggering)
– Defines a percentage of the whole memory content. This part of the memory
content is filled with measured values before the triggering (see Fig. 9-126).
0 % ... 999.9 % • Positive trigger delay (post triggering)
– Defines a percentage of the whole memory content. The saving of the measured
values after triggering is delayed by this part of the memory content (Fig. 9-125).
Sampling period C0738 1 ms ... 10 min • Setting of the sampling period
– The sampling period is the time between two measurements
– The measurements are carried out simultaneously for all channels (e. g. is
measured value at channel 1 is measured at the same time as a measured value
at channel 2, 3 or 4.
– The sampling period can be set in steps of 1, 2 and 5.

memory
C0740/1 0 ... 16383 • Defines the starting point for reading the data memory and thus enables the memory
array to be deliberately accessed.
– In order to read the data memory b it by bit (e. g. reading only the measured value
of a channel or reading with reduced memory depth), the starting point can be
changed.
C0740/2
1 • Enable “Read memory”
– Enables the access to the memory to read the data
0 • Inhibit “Read memory”
– Inhibits the access to the memory. The access must be inhibited after every
reading of the data
