12.4.5 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!

As soon as the oscillogram does not show the complete measurement anymore, a scrollbar

appears below the time axis. The scrollbar serves to move the visible cutout horizontally.

The labelling of the time axis and the position display are automatically updated when the

cutout is moved.

Selection of the horizontal display position

The Position input field serves 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.

Changing the time base subsequently

Change the time base to stretch or compress measurements that have already been completed.

Zoom function

 Go to the oscilloscope toolbar and click the icon to activate the zoom function.

Zoom function Procedure

shift of selection
