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 3-7 . Do not tighten the connection further.
CAUTION 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.
Connecting the Sliding Load
Use this procedure to connect the sliding load to a test port or a 7 mm cable connector.
CAUTION
Circuitry inside the test set at the test ports may be destroyed if precautions are not
taken to avoid electrostatic discharge (ESD). During this procedure, the center
conductor of the sliding load is connected to the exposed center conductor of the test
port. Ground yourself to prevent electrostatic discharge.
CAUTION The sliding load center conductor can be damaged if the sliding load is not in line when
mating the load to a connector. Always line-up the sliding load when connecting or
removing it from a connector.
1.
Refer to Figure 3-8 . Extend the threads on the test port adapter or cable connector and retract
the threads on the sliding load. Insert the center conductor tip into the hole in the sliding load
center conductor. Do not insert a collet in this hole.
