The console contains information about units and limit values of the selected parameter. There are three methods to
set limit values:

Manual the range is fixed by operator; the operator is allowed to set the limits of Y axis values with the Min and Max
buttons; the buttons appear on the console just after the mode has been selected; the current values are displayed on
the right side of the proper button (see Figure 5.31);
Full Range in this case the range is calculated automatically within minimum and maximum permissible values.

5.8.1.3 Time axis
There are two modes to display a trend: Actual and History.
NOTE!
All time settings are general for all trends. It means that whenever
changes occur, all trends apply them.
The initial(end-limit) time point is at the right bottom of diagram.
In case of Actual mode the end-limit value is the current time and the time interval gets back as negative values.
The units(hr, min,s)are displayed at the initial point.
The History mode allows selecting the end-limit point (the
End button). In this case the static diagram is displayed
for the selected interval with the end-limit point. The units are displayed at the first interval value.
To switch to the graphic mode click OK . If the changes shouldn’t be applied click Cancel .
In case of the History mode the diagram can be moved along the time axis by clicking on the arrow buttons that appear
at the bottom right and bottom left after clicking on the proper background spots (see Figure 5.32).
