10.1.2.2 Sampling Period
To plot a graph, set the sampling period for the measurement data.
This graph allows the plotting of 60 data points per graduation on the time axis. For example, a ten-
second sampling period, graduation corresponds to 600 seconds (Figure 10-5). The sampling periods
range from 1 to 30 seconds allowing time history ranging from 5 to 150 minutes.
