User manual - DATA RECORDER SRD-99 and cooperating software
The display shows points corresponding to measurement results. Directly after switching
to the "
Graph
" mode the display shows points of the graph corresponding to measurement
results recorded so far. The points that are displayed next, correspond to the results of
conducted measurements. Therefore, if there are recorded measurement results in the unit's
memory, they shall be displayed directly after switching to the "
Graph
" mode, otherwise (no
recorded measurements) the graph points corresponding to measurements results shall be
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 (
). 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. 6.19. 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.

Changes of settings configuring the operation of a given channel and operation stoppage are
signalled in the form of a vertical line (
