Sample length: Per floppy disk during manual save
Display data file only:
When the number of control loops is 2; the number of
measurement CH is 10; the number of computation CH is
8; and display update rate is 30 min./div (data save
interval is 60 s)
Number of data points per CH = 1,2000,000 bytes/(6 × 4
bytes + 10 × 4 bytes + 8 × 8 bytes) = Approx. 9,375 data
points*
* Maximum number of data points is 100,000.
Sampling length per file = 9,375 × 60 s = 562,500 s =
Approx. 6 days
Event data file only:
When the number of control loops is 2; the number of
measurement CH is 10; the number of computation CH is
8; and display update rate is 1 s
Number of data points per CH = 1,2000,000 bytes/(6 × 2
bytes + 10 × 2 bytes + 8 × 4 bytes) = Approx. 18,750 data
points*
* Maximum number of data points is 120,000.
Sampling length per file = 18,750 × 1 s = 18,750 s =
Approx. 5 hours
Display data file + event data file
Display data file size = 900,000 bytes
Up to 75,000 data points
Event data file size = 300,000 bytes
Up to 30,000 data points
When using a Zip drive or an ATA memory card, the file size
varies depending on the storage capacity of the medium.
