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.
