6 MEASUREMENT DATA ANALYSIS
6.1.5 Reference Marker Feature
Reference marker feature allows the user to view the data relative to the reference
marker. Other marker readings are represented as delta relative to the reference marker.
The reference marker shows the absolute data. The reference marker is indicated with ∆
symbol instead of a number (See figure 6.2). Enabling of a reference marker turns all
the other markers to relative display mode.
Reference marker can be indicated on the trace as follows:
Ñ symbol of the active reference marker on a trace;
symbol of the inactive reference marker on a trace.
The reference marker displays the stimulus and measurement absolute values. All the
rest of the markers display the relative values:
§stimulus value — difference between the absolute stimulus values of
this marker and the reference marker;
§measured value — difference between the absolute measurement values
of this marker and the reference marker.
To enable/disable the reference marker, use the following
