Voltage source test leads
When using the voltage source, the test leads must be rated for 505V minimum and should
include safety sheaths. These test leads are recommended for use with the Model 6487:
Model 8606 High Performance Probe Tip Kit — Consists of two spade lugs, two alliga-
tor clips, and two spring hook test probes. (The spade lugs and alligator clips are rated at
30V RMS, 42.4V peak; the test probes are rated at 1000V.) These components are
designed to be used with high performance test leads terminated with banana plugs, such
as the Model 8607 High Performance Banana Cables.
Model 8607 High Performance Banana Cables — Consists of two high voltage (1000V)
banana cables. The cables are terminated with banana plugs that have retractable sheaths.

Use only test leads with a minimum rating of 505V peak for connec-
tions to the voltage source to avoid a possible shock hazard.
Basic connections to DUT
Current measurement connections
Basic connections for current measurements are shown in Figure 2-3 ; the DUT is the
current to be measured. Circuit high is connected to the center conductor of the input
connector and circuit low is connected to the connector’s input LO (inner shield).
