Historical graphs
Graphs are used to display the history of the values recorded and to provide an easy visual
method of spotting variations and trends in the recorded values over time. The following
historical graphs are available, with a point for each opening or closing operation:
• Reaction time (t1) for each pole
• Operating time (t2) for each pole
• Contact separation speed for each pole
• DC voltage (source 1 and 2)
• Ambient temperature
The last two are provided to spot if voltage or temperature had an obvious effect on a
particular historical value measured.
The graphs can be found in the Operations Charts section:
