Automatic scaling function
Use the automatic scaling function to automatically scale and reposition the representation of
selectable signal characteristics in the oscillograph and reset the offset to "0".

How to carry out automatic scaling:
1. Go to the Data logger toolbar and click the icon to activate the automatic scaling
function.
2. Select the channels/parameters for automatic scaling in the Select variable dialog box.
3. Press OK.
• The dialog box is closed and the selected channels/variables are scaled automatically.
7.7.2.7 Reading individual measured values
In addition to the zoom and scaling function, the data logger offers a "cursor function" that can be
used to display individual measured values of a selectable channel or the difference between two
measured values.
• If the Cursor has been pressed, the cursor function is active and two movable vertical measuring
lines are shown in the diagram.

How to use the cursor function:
1. Click the Cursor button.
2. Select the channel for which individual measured values are to be indicated from the
Channel list field.
3. Hold down the left mouse button and drag the red vertical measuring line to the desired
position.
• The active measuring line is represented by a continuous line, the inactive measuring
line is represented by a dotted line.
• If you position the mouse pointer over the inactive measuring line, the measuring line
automatically becomes active.
• The value measured at the position of the active measuring line is indicated in the Value
group field.
• The difference between the values measured at the two measuring lines is indicated in
the Differential value group field.
7.7.2.8 Comparing peak values
This function is available from »Engineer« V2.10!
Several values displayed in the data logger can be compared to each other using a horizontal
measurement line.
• The horizontal measurement line is displayed when the Cursor button has been pressed.
• The measurement line is automatically created based on the current cursor point and thus
cannot be shifted.
