DC 5A Range

A,B: Input exceeds the ADC dynamic range.

C,D: The DCI offset causes the input to exceed the
upper ADC dynamic range.

E: The DCI offset causes the input to exceed the
lower ADC dynamic range.

The DC current range should be manually selected
when the following conditions are true:

When DCI measurement is used.

When the signals being measured contain both
DC and AC components.

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 the auto-range function.
