Use, Maintenance, and Care of the Devices
Handling and Storage
3. Apply downward force perpendicular to the wrench handle. See Figure 3-6 . 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 3-6 . 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.
Do not pivot the wrench handle on your thumb or other fingers, otherwise you apply an
unknown amount of torque to the connection when the wrench reaches its break point.
Do not twist the head of the wrench relative to the outer conductor mating plane. If you
do, you apply more than the recommended torque.
How to Separate a Connection
To avoid lateral (bending) force on the connector mating plane surfaces, always support the
devices and connections.
CAUTION
Turn the connector nut, not the device body. Major damage to the center
conductor can occur if the device body is twisted.
1. Use an open-end wrench to prevent the device body from turning.
2. Use the torque wrench to loosen the connector nut.
3. Complete the separation by hand, turning only the connector nut.
4. Pull the connectors straight apart without twisting, rocking, or bending either of the
connectors.
Handling and Storage
• Install the protective end caps and store the calibration devices in the foam-lined
storage case when not in use.
• Never store connectors loose in a box, desk, or bench drawer. This is the most common
cause of connector damage during storage.
• Keep connectors clean.
• Do not touch mating plane surfaces. Natural skin oils and microscopic particles of dirt
are easily transferred to a connector interface and are very difficult to remove.
• Do not set connectors contact-end down on a hard surface. The plating and the mating
plane surfaces can be damaged if the interface comes in contact with any hard surface.
