Range Note:
DC currents with AC components cannot be accurately
measured if the DC+AC component exceed the ADC
dynamic range for the selected DC range. Any current
exceeding the ADC dynamic range will be clipped at the
upper/lower range limit. Under these conditions the
range that is chosen with the Auto range function may be
too small.

DC 1mA 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.
