Appendix 2 Relationship between the Chart Speed,
Sample Rate and Record Length in
Recorder Mode
The relationship between the chart speed, sample rate, and record length during Chart
Recorder mode (see chapter 9) is as follows:
Chart Speed Sample Rate Record Length Maximum Number Record Time

The sample rates in the table above are the data acquisition rate to the internal memory
when the acquisition mode is set to normal.
If the acquisition mode is set to envelope, the data is acquired at the maximum sample
rate of each input module. Then, the maximum and minimum values are determined over
each interval defined by the sample rate in the table above and stored in the internal
memory.
