This key is used to browse through the various accessible screens containing all information available before, during or after
the measurement. Depending on the measurement mode and the configuration chosen (CONFIG key), the screens are different.

At the end of each measurement, pressing the GRAPH key displays the curve of variation of the insulation resistance
versus time.
Insulation resistance axis.
Time axis.
Curve R(t), solid line.
Minimum and maximum values
of the voltage and the resistance
and time at the location of the
cursor.
Test voltage axis.
Curve V(t), dotted line.
This curve is plotted using samples recorded during the measurement.
The
keys are used to move along the curve to display the exact values of each sample.
The minimum and maximum values may be the same if the time scale of the graph is too short.
In the case of a measurement in U-RAMP or U-STEP mode, this gives:
