The DC current range should be manually selected when
the following conditions are true:
1.
When DCI measurement is used.
2.
When the signals being measured contain both DC
and AC components.
3.
When the amplitude of the AC component in the
measured signal is higher or lower than the dynamic
range of the range being currently selected by
auto-range function.
