CAUTION
The 5355A contains metric threaded HP-IB cable mounting studs as
opposed to English threads. Metric threaded HP 10631A, B, C, or D
HP-IB cable lockscrews must be used to secure the cable to the
Instrument, identification of the two types of mounting studs and
lockscrews is made by their color. English threaded fasteners are
colored silver and metric threaded fasteners are colored black. DO
NOT mate silver and black fasteners to each other or the threads of
either or both will be destroyed. Metric threaded HP-iB cable
hardware illustrations and part numbers follow.
