4.2.2. GRAPH SECONDARY FUNCTION
This function is used to display the insulation resistance versus measurement time curve after a time-
limited measurement (Timed Run or Timed Run + DD).
This curve is plotted from the samples recorded during the measurement. The
can be used to move along the curve to display the exact values of each sample.
