Torquing the Connection
Connectors must be correctly torqued to their required settings to make sure the connector is tight enough to
ensure an accurate RF measurement but not so tight as to damage the connector or the instrument. Use the
correct torque wrench for the connector type. Applying proper torque will improve connection repeatability and
reproducibility. Over torquing connectors is destructive as it may damage the connector center pin. Never use
pliers to tighten connectors.
1.
Select a torque wrench of proper size and rating for the connector and an open end wrench. The open end
wrench is used to prevent the body of the connector from turning. Refer to
for torque
specifications.
2.
Place the two wrenches at an angle of less than 90° as shown in
3.
Hold the torque wrench at the end as shown in
.
Caution
Using two wrenches with an angle greater than 90° causes the devices to lift up, which tends to
misalign and stress the connectors. This becomes more of a problem when multiple devices are
connected together.
Breaking the handle fully can cause the wrench to kick back which may loosen the connection.
Figure 9-11.
Using Wrenches at Proper Angle
Caution
Holding the torque wrench anywhere but at the end applies an unknown amount of torque and can
damage contacts and/or connectors.
