GRAPH WINDOW
Along with the insulation resistance value and related parameters the meter also shows
a trend of the insulation resistance of the DUT over time. This is a very important feature as
the trend of the insulation resistance gives a lot of information about the condition of the
insulation. In the graph there can be a maximum of 300 data points. The interval between
each data point depends upon the test duration. Table shows the test duration and the
corresponding interval between each data point.
