Sampling Interval
To plot a graph, set the "Sampling interval" for the measurement data.
This graph allows the plotting of 60 data items on one division on the time axis. So, if you set
a ten-second sampling interval, one division corresponds to 600 seconds (Figure 10.5). The
allowable sampling intervals range from 1 to 30 seconds. If you set a one-second sampling
interval, the axis of the abscissas then corresponds to five minutes.
If you set it to 30 seconds, the axis of the abscissas then corresponds to 150 minutes.
