Using a torque wrench guarantees that the connection is not too tight, preventing possible connector
damage. It also guarantees that all connections are equally tight each time.
Prevent the rotation of anything other than the connector nut that you are tightening. It may be possible to
do this by hand if one of the connectors is fixed (as on a test port). However, it is recommended that you use
an open-end wrench to keep the body of the device from turning.
1. Position both wrenches within 90 degrees of each other before applying force. See
opposing each other (greater than 90 degrees apart) will cause a lifting action which can misalign and
stress the connections of the devices involved. This is especially true when several devices are
connected together.

2. Hold the torque wrench lightly, at the end of the handle only (beyond the groove). See
Figure 3-7 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.
