8.5 Data-isoGraph
The isoGraph represents the chronological sequence of the insulation resistance over
time. This graphical representation can be displayed over the following time periods:
hour, day, week, month and year.
The measured values for individual representations are stored in a separate memory. Up
to 100 measured values are available to represent each graph. and the resolution of each
graph is determined by these values.
