plotted from the time this mode is switched on. If the measurement result for the given channel
exceeds the
graph scale range
, then instead of the graph point corresponding to the
measurement result, the display shows an arrow indicating the direction of exceeding the
range (
Fig.
6.19
,
6.20
). Above the upper limit of graph window the display shows points
corresponding to the measurement recording times. The vertical scale of the graph covers the
values defined for the
graph scale range
.
Fig. 6.20. Exceeding lower limit of the graph scale range
In the case of recording averaged values all points of the graph, concerning values
recorded in the unit's memory, constitute averaged measurement results. Indicators (numeric,
bar) and points of the graph, corresponding to current values refer to the momentary
measurement value.
When recording averaged measurement results exceeding the
allowable measurement
range
is understood as exceeding of this range by at least one of the measurements to be
averaged.
In the case of the upper limit, lower limit, or both limits of measurement range being
exceeded in the given
recording period
, values represented in the form of arrows indicating
the direction of exceeding (up, down, or both directions) will be recorded in the unit's memory
instead of the averaged results.
Fig. 6.21. Breaks in registration or change of configuration in "Graph" mode
Changes of settings configuring the operation of a given channel and operation stoppage
are signalled in the form of a vertical line (
Fig.
6.21
).
If the settings of the horizontal scale (time scale) will be too big (time/point) in relation
to speed of changes of the measurement signal, the graph can become illegible. If
this is the case, change the time scale settings. The horizontal scale settings (time
scale) can be changed in the "
Graph options
" menu. In order to go to the
"
Graph options
" menu press the
[ESC/MENU]
key.
