Use, Maintenance, and Care of the Devices
Connections
3. Apply do wnwa rd force perpend icular to the wrench handle . See Fi gu re 3- 8 . This applies
torque to the connection through the wrench.
Do not hold the wrench so tightly that you pus h the handle straight down along its
length rather than pivoting it, otherwise you apply an unknown am ount of torque.
4. Tighten the connection just to the torque wrenc h break point. The wrench handle gives
way at its internal pivot point. See Figure 3-8. Do not tighten the connection f urther.
CAUTION You don’t have to fully break the handle of the torque wrench to reach the
specified torq ue; doing so can cause the handle to kick back and loosen the
connection. Any give at all in the handle is sufficient torque.
Do not pivot the wrench handl e on your thumb or other finger s, otherwis e you apply an
unknown amount of torque to the connection when the wrench reaches its break point.
Do not twist the hea d of the wrenc h r el ati ve t o the outer conductor mating pla ne. If yo u
do, you apply more than the recomm ended torque.
Connecting the Sliding Load
Use this procedure to connect the sliding load to a test port or a type-N cable connector.
NOTE The sliding load uses a plastic centering bead to support its center conductor
when pin depth is adjusted and gaged and when the load is stored. Remove
this support bead from the sliding load before you connect the load for an
electrical calibration. Reinsert this support bea d when you’ve finished using
the sliding load.
CAUTION Circuitry inside the test set at the test ports may be destroyed if p recautions
are not taken to avoid electrostatic discharge (ESD). During this procedure,
the center conductor of the sliding loa d 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 dama ged if the sliding load is not
held in line when mating the loa d to a c onnector. Always line up the sliding
load when connecting or removing it from a connector.
1. Refer to Figure 3- 9. Loosen the center conductor pull- back nut completely. Press the
center conduc tor cap to ex tend the center c onductor of the sliding l oad beyond the end of
the connector.
2. Continue to pr es s t he c enter co nductor c ap a nd mate the c enter c onduct or o f t he s lid ing
load with the cable/test port connector’s center conductor.
