Safety
Shield
Each 2602 chassis is connected to chassis
earth ground through the power cord.
WARNING
Connect metal safety shield
to Safety Earth Ground using
#18 AWG or larger wire.
Note
On the 2602-1, connect Channel A
LO to the Chassis at the rear panel.
LOs for the other channels must be
isolated from Chassis.
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.
