Service manual

Connecting a Cable

1. Ground yourself and

all

devices (wear a grounded wrist strap,

to a Test Port

and work on a static mat).

2. Visually and mechanically inspect the connectors.

necessary, clean the connectors.

4. Carefully align the connectors. The male connector center pin

must slip concentrically into the contact fingers of the

female

connector.

5. Push the connectors straight together.

Do not

twist or screw

them together. As the center conductors mate, there is usually a

slight resistance.

Caution

not

twist one connector into the other (like inserting a light

bulb). This happens if you turn the device body rather than the

connector nut.

6. The preliminary connection is tight enough when the mating

plane surfaces make uniform, light contact. Do not over tighten.

7. To assure consistent torque in the following steps, relieve any side

pressure on the connection.

8. Using the spanner wrench supplied with the HP 8510, hold the

cable stationary (see Figure A-1 for wrench placement).

9. Using a 20 mm (8 in-lb) torque wrench, tighten the connection

(see Figure A-l for wrench placement).

10. Using an anti-rotation clamp (supplied with the test set), secure

the

cable to the test

set.
