Figure 3-8 Using the Torque Wrench
3. Apply downward force perpendicular to the wrench handle. This applies
torque to the connection through the wrench.
Do not hold the wrench so tightly that you push the handle straight down
along its length rather than pivoting it, otherwise you apply an unknown
amount of torque.
4. Tighten the connection just to the torque wrench break point. The wrench
handle gives way at its internal pivot point. See Figure 3-8 . Do not tighten
the connection further.
Connecting the Airline
Before making the connection, refer to “Preliminary Connection” on
page 3-16 .
Cables with the appropriate adapters on the ends should be connected to
PORT 1 and PORT 2 of the network analyzer.
1. Remove the center conductor from its plastic case. Make sure you select
the correct center conductor for the airline you are connecting. Refer to
Figure 2-3 and Figure 2-4 on page 6 for illustrations of both center
conductors.
You don’t have to fully break the handle of the torque wrench to reach the
specified torque; doing so can cause the handle to kick back and loosen
the connection. Any give at all in the handle is sufficient torque.
Before making any connections to the test set, be sure that bias power to
the test set is off, and take care to avoid electrostatic discharge. Refer to
“Electrostatic Discharge” on page 3-1 .
Wear gloves while performing the following procedure. You will be
touching the exposed center conductor of the airline. It is important that
you do not transfer oil and dirt from your fingers to this center conductors.
Refer to “Handling and Storage” on page 3-21 .
