z  Selecting the axis: The axis is selected in the Axis toggle field. 
z  Signal type: 
Velocity setpoint 
Actual position value of measuring system 1 
Following error 
z  Determining the measuring time: The measuring time is entered in ms 
directly in the “Measuring Time” input field. 
z  Determining trigger time to or after 
    With input values < 0, recording starts by the set time prior to the trigger event, 
and with values > 0 accordingly after the trigger event, whereby the following 
conditions must be observed: 
Trigger time + measuring time ≥ 0. 
z  Selecting the trigger condition: Position the cursor on the Trigger 
Condition field and select the condition using the toggle key. 
—  No trigger, i.e. the measuring starts immediately after pressing the Start 
softkey. 
—  Negative edge. 
—  Exact stop fine reached. 
—  Exact stop coarse reached. 
z  Determining the trigger threshold: The threshold is entered directly in the 
Threshold input field. It acts only for the trigger conditions “Positive edge” 
and “Negative edge”. 
Press “Marker” key to branch to another softkey level, in which the horizontal 
or vertical marker can be switched on or off. The markers are displayed in the 
status bar. 
   The markers are moved in steps of one increment by means of the cursor 
keys.  Larger step widths can be set in the input fields. The value specifies 
the number of raster units per <SHIFT> + cursor movement by which the 
marker is to be moved. 
    If a marker reaches the margin of the diagram, the next raster in horizontal or 
vertical direction is automatically pulled down.
