Because there are a lot of parameters to be displayed they have been divided into
three sub screens which can be scrolled using the scrolling arrows. Figure shows the
sequence of the screens along with the parameters displayed on the corresponding
screen.

a message will appear to tell you about the file number. You can press the OK button on
the message box in order to go back to the measurement screen.
5.4 Step Mode:
In the step voltage test 5 test voltages are applied to the DUT. The SV test is based on
the principle that an ideal insulator will produce identical readings at all voltages, while an
insulator which is being over stressed, will show lower insulation values at higher voltages.
This test is divided into 5 intervals.
