Care and Handling of Precision Connectors

Counter-Rotation Technique
The recommended Hewlett-Packard counter-rotation technique is for precision
3.5 mm connectors. Before making any connections to the channel connectors,
ground yourself with a grounded wrist strap. Also, it is good practice to grasp
the outer shell of the test port before you make any connections to the channel
connectors in order to discharge any static electricity on your body. This is the
most effective single safeguard to prevent ESD damage to your instruments.
1
If the device has a retractable connector nut, fully retract the nut before
mating the connectors. Carefully align the male and female contact pins
and slide the connectors straight together until the center and the two
outer conductors meet. Be careful not to twist or bend the contact pins.
You should feel a slight resistance as the connectors mate.
2
Make the preliminary connection by attaching the connector nut of the
male connector to the female. The male connector is held stationary
as the female connector is tightened and draws the male pin into the
female connector. Refer to Figure 2-9. Any other method used may
cause the male pin to damage the female connector. Support the body
of the device and turn the connector nut until the mating surfaces make
light contact. Do not overtighten. All you want is a connection of the
outer conductors with gentle contact at all points of both mating
surfaces.
