Disconnection - Agilent Technologies 346A Operating And Service Manual

Table A-2 Recommended Torque Settings
Type Description
Precision 12 lb-in (136 N-cm.)
7mm
Precision 8 lb-in (90 N-cm)
3.5mm
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.
