Function Description Selection Code
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. 3−126).
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. 3−125).
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. value
measured at channel 1 is measured at the same time as the measured value at
channel 2, 3 or 4.
– The sampling period can be set in steps of 1, 2 and 5.
Number of
Channels C0739 Number of channels used for measurements.
Read data
memory The code is required if the GDC is not used for the visualisation.
C0740/1 0 ... 16383
·
Defines the starting point for reading the data memory and thus enables the memory
array to be selectively accessed.
– In order to read the data memory bit by bit (e. g. reading only the measured values
of one 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
