2
Enables you to set the display channel.
The channel which can be set differs according to the display items and wiring settings.
3
Set the type of graph to be displayed.
The type that can be set differs according to the display items.
MAX The maximum value during the recording interval is displayed.
AVG The average value during the recording interval is displayed.
MIN The minimum value during the recording interval is displayed.
ALL
The maximum, average, and minimum values during the recording interval
are displayed.
4
Set the zoom factor for the vertical axis of the graph.
Auto, ×1, ×2, ×5, ×10, ×25, ×50
5
Set the zoom factor for the horizontal axis (time axis) of the graph.
The horizontal axis (time axis) which can be set, differs according to the recording intervals.
