The display period of this graph is one minute. Since the period of the record is one second, each point on the graph
corresponds to a value recorded in a one-second window once per minute. There is therefore a substantial loss of
information (59 values out of 60), but the display is rapid.
NOTE: Values of the cursor in red indicate saturated values. Black dashes indicate erroneous values. Red dashes
indicate values that are not calculated (following the end of calculation of the MIN-MAX-AVG mode when
pressed).

2 Changes the scale of the display between 1 minute and 5 days
The display period of the graph shown in Figure 5-48 is one minute. With the MIN-AVG-MAX mode activated, each point
of this graph represents the arithmetic mean of 60 values recorded every second. This graph is therefore more precise
than the graph shown in Figure 5-47, since there is no loss of information. It is slower, however.
To stop the calculation of the MIN-AVG-MAX mode, press
NOTE: While MIN-AVG-MAX mode is being calculated, a progress bar is displayed for this calculation in the status
strip instead of the recording display window positioning bar. The MIN-AVG-MAX mode is not available while a trend
is being recorded.
