Display Reference Position
The most recent data is located at the reference display position.
Expanding/Reducing the Time Axis
The time axis can be expanded or reduced with respect to the “display reference
position.”
Display data: 2 times the trend display to 1/60 minimum
Event data: Reduction only, up to 1/60 minimum
The minimum magnification and the factor by which the display can be expanded or
reduced with one operation vary depending on the display update rate for the display
data and on the sampling interval for the event data. To expand or reduce the display
further, repeat the procedures.
