SMA
5 lb-in (56 N-cm) Use the SMA wrench to connect male
SMA connectors to female precision 3.5min connectors.
Connections of male precision 3.5mm. connectors to female
SMA connectors can be made with the precision 3.5mm
torque wrench (8 lb-in).
Type-N
Type-N connectors may be connected finger tight. If a
torque wrench is used, 12 lb-in (136 N-cm) is
recommended.
To reiterate the main do's and do not's detailed previously:
•
Avoid holding the wrench tightly, in such a way that the handle is not pivoted
but simply pushed downward the same amount throughout its length. If this is
done, an unlimited amount of torque can be applied.
•
Hold the wrench at the same point near the end of the handle every time, and
always in the same orientation. Whenever possible, begin tightening the
connection with the wrench held horizontally
Disconnection
Disconnect connectors by first loosening the connector nut that was tightened in
order to make the connection. If necessary, use the torque wrench or an open-end
wrench to start the process, but leave the connection finger tight. At all times
support the devices and the connection to avoid putting lateral (bending) force on
the connectors.
Complete the disconnection by disconnecting the connector nut completely.
Never disconnect connectors by twisting one connector or device out of the other as
one might remove a screw or a light bulb. This is extremely harmful and connector
