Model 6487 Reference Manual
To allow many parallel connections to one instrument, stack the connector. Two screws are
located on each connector to ensure that connections remain secure. Current standards call
for metric threads, which are identified with dark-colored screws. Earlier versions had dif-
ferent screws, which were silver-colored. Do not use these types of connectors on the
Model 6487, because it is designed for metric threads.
Figure 9-2
To avoid possible mechanical damage, stack no more than three connectors on any one
unit.
