Determining the measuring time: The measuring time is entered in ms
directly in the "Measuring Time" input field.
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.
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.
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.
