Using Delta Markers
In the delta marker mode, only active markers will be visible. The delta marker
feature displays the difference (delta) in both frequency and value between the
selected marker and each active marker. If the limit line is active, the difference
between the selected marker and the limit line will be evident. The frequency
difference between the selected marker and the limit line will always be the fre-
quency of the marker. All markers follow the current trace only.
Note: The delta marker feature compares points only on one trace,
and must have at least two active markers for the delta option to work.
Note: Ensure that unit is in either Measure Match mode or Fault
Location mode.
1. Press the Marker key to enter marker setup.
2. Press the Mark softkey to select an active marker (1-6).
3. Press the Delta softkey to cycle through the active markers and limit line (if active).
4. Press the Esc key to return to the test screen.
