User’s Manual Remote Operations 14-5
To allow many parallel connections to one instrument, stack the connectors. Two screws
are located on each connector to ensure that connections remain secure. Present standards
call for metric threads, which are identified with dark-colored screws. Earlier versions
have different screws, which are silver-colored. Do not use these types of connectors on
the SourceMeter; it is designed for metric threads.
Figure 14-2 shows a typical connecting scheme for a multi-unit test system.

IEEE-488 connections
To avoid possible mechanical damage, stack no more than three connectors on any one
unit.
NOTE To minimize interference caused by electromagnetic radiation, use only shielded
IEEE-488 cables. Available shielded cables from Keithley are Models 7007-1
and 7007-2.
