Use, Maintenance, and Care of the Devices
Using a Torque Wrench
Using a Torque Wrench
Use a torque wrench to make a final connection. Table 3-2 provides
information about the torque wrench recommended for use with this
calibration kit. Refer to Table 6-1 on page 6-2 for part number and ordering
information.
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. Table 3-9 on page 3-16 shows you where to hold
the torque wrench for optimum performance.
1. Use the torque wrench supplied with your kit to make the final
connections.
2. Rotate only the connector nut when you tighten the connector.
In all situations, use an open–end wrench to keep the body of the device from
turning. Position both wrenches within 90 degrees of each other before
applying force (see Table 3-10 on page 3-16 ). Wrenches opposing each other
(180 degrees apart) will cause a lifting action. This lifting action can misalign,
and stress the connections of the devices involved. This is especially true when
several devices are connected together.

Do not pre-tighten the connector nut so much that there is no rotation of
the nut with the torque wrench. Static friction must
not
be present during
torquing.
