The following two file types can be created.
• Event data file (stores instantaneous values acquired
periodically at a specified sampling interval)
• Display data file (stores the maximum and minimum
values for each sampling interval from among measured
data acquired at scan intervals)
Files can be created in the following combinations.
(a) Event data file (only for trigger mode) + display data file
(b) Display data file only
(c) Event data file only
Data format : Binary
Data size per channel :
Display data : Measurement data...4 bytes/datum,
computation data...8 bytes/datum
Event data : Measurement data...2 bytes/datum,
computation data...4 bytes/datum
Event data : Selectable from Free, Trigger or Rotate
Display data + Event data : Selectable from Trigger or Rotate
The sampling length(the maximum data length) can be
derived from the following equation.
Sampling length = the maximum number of data points per
channel × sampling interval
Maximum number of data points per channel : calculated
from internal memory capacity, types of data, data size,and
number of measurment or computation channels data to be
stored
