NOTE
Each stacked channel adds approximately 100μA of
common mode current that is seen by the channels below it.
Therefore, in the example above, Model 2602-1 Chan A will
measure approximately 100μA x 3 = 300μA higher than
Model 2602-2 Chan B. Similarly, Model 2602-1 Chan B will
measure approximately 100μA x 2 = 200μA higher than
Model 2602-2 Chan B. The most accurate measurement of
actual current flowing through the DUT will be obtained from
Model 2602-2 Chan B.
