• The next start trigger is not accepted until saving of the file to Memory Card is completed. When
the save is completed, BUSY output turns ON.
• Data can be sampled at high speed during logging as data is buffered to internal RAM on the ZS-
DSU without the Memory Card being accessed.The size of data that can be saved continuously
without any omissions is affected by the size of the internal RAM on the ZS-DSU.
The following tables show an approximate guide to sampling intervals and logging time:
