Appendix 1 Time Estimate for Writing Display/
Event Data to the Internal Memory
This section describes the number of data points of the display data/event data that can
be acquired and the sampling length. Use the information when determining the amount
of time it takes for the internal memory to become full or when deciding the channels to
be acquired or the sampling interval.
The possible range of menus of the auto save interval of display data and the data length
of event data is displayed in the soft keys based on the information described here.
Maximum Sampling Length
Data Format
The display data have minimum and maximum values for each sampling interval.
Event data consists of instantaneous values.
The number of data bytes per channel is shown in the following table.
Data Type Measurement Channel Computation Channel
Display data 4 bytes/channel 8 bytes/channel
Event data 2 bytes/channel 4 bytes/channel
• Example
Data format when the data of measurement channels 1 to 4 and a computation
channel 31 are acquired.
