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.
