13.4.5 Adjusting the representation
After the variable values have been recorded and the online data record has been transferred to the
PC, the data record is visualised in the oscillograph. If required, the representation can now be
adjusted by using the zoom or the automatic scaling function.

Tip!
When the oscillogram does not show the complete measurement, a scrollbar appears
below the time axis. You can use this scrollbar for horizontal scrolling of the visible area.
The labelling of the time axis and the position display are automatically adapted.
Selection of the horizontal display position
The Position input field can be used to change the horizontal display position.
• The position value can be directly entered into the input field or selected using the arrow
buttons.
• When the arrow buttons are used and the <Ctrl> key is pressed, you can increase the step size
to accelerate the shift.
Subsequently changing the time base
Change the time base to stretch or compress measurements that have already been completed.
