• Display data and event data
Measurement channel : 2, computation channel : none
Data Maximum Number of Data Points and Sampling Length
Display data Maximum number of data points = 900,000/(2 CH
×
4 bytes + 0
×
8 bytes) =
112,500
However, since 75,000 data points is the limit,
Maximum number of data points = 75,000
Display rate When set to 30 min/div (60 s sampling interval)
Sampling length = 75,000 data points
×
60 s = 4,500,000 s (approx. 52 days)
Event data Maximum number of data points = 300,000/(2 CH
×
2 bytes + 0
×
4 bytes) =
75,000
However, since 30,000 data points is the limit,
Maximum number of data points = 30,000 data points
When the event data sampling interval is 1 s
Sampling length = 30,000 data points
×
1 s = 30,000 s (approx. 8 hours)
Measurement channel : 12, computation channel : 6
Data Maximum Number of Data Points and Sampling Length
Display data Maximum number of data points = 900,000/(12 CH

Display rate When set to 30 min/div (60 s sampling interval)
Sampling length = 9,375 data points

When the event data sampling interval is 1 s
Sampling length = 6,250 data points
×
1 s = 6,250 s (approx. 1.7 hours)
