Auto (2):
After the scope system is reset Data Logger Data Not Ready (Y12) is set to 1 and the scope begins to acquire data. Once the buffer is full Data
Logger Data Not Ready (Y12) is set to 0 and the scope continues to acquire data. Data Logger Arm (Y11) has no effect on data acquisition. Provided
Data Logger Data Not Ready (Y12) = 0 and Data Logger Saving Data (Y13) = 0 it is possible to read the data from the scope buffer as a scope file.
Data acquisition is stopped when the file transfer begins. When the file transfer is complete, data acquisition begins again and Data Logger Data Not
Ready (Y12) is set to 1 for a period that is long enough to fill the scope buffer with new data.

Data Logger Sample Time (Y14) defines the sample rate of the scope function for all traces in 250 μs units (i.e. if Data Logger Sample Time (Y14) =
4, the sample time is 1 ms).
Data Logger Trigger Delay (Y15) defines how much data is stored before and after the scope is triggered. If Data Logger Trigger Delay (Y15) = 0 %
then no data is stored before the trigger and all the data is after the trigger. If Data Logger Trigger Delay (Y15) = 100 % then no data is stored after the
trigger, but all the data is before the trigger.
