Basic connections to DUT
Current measurement connections
Basic connections for current measurements are shown in
rent to be measured. Circuit high is connected to the center conductor of the input connec-
tor and circuit low is connected to the connector’s input LO (inner shield).

Basic current measurement connections
WARNING
If it is possible for the DUT or external supply to present more than
505V to the input HI, it is imperative that the connection between
input LO and the external voltage source be sufficiently low impedance
and capable of carrying the short-circuit current of the source, in order
that the LO not exceed 505V.
CAUTION
Current limiting resistors are required for DUTs capable of forcing
voltages 505V or greater. Damage to the instrument may result if volt-
ages greater than 505V are forced on the Model 6487 INPUT HI.
Ohms measurement connections
Basic connections for ohms measurements are shown in
; the DUT is the resis-
tance to be measured. Circuit high is connected to the center conductor of the INPUT con-
nector and circuit low is connected to the V-SOURCE OUTPUT HI terminal. Note that
INPUT LO and V-SOURCE OUTPUT LO are connected together externally.
