Making Connections

Making Connections
Good connections require a skilled operator. Instrument sensitivity and coaxial
connector mechanical tolerances are such that slight errors in operator
technique can have a significant effect on measurements and measurement
uncertainties.
The most common cause of measurement error is poor connections.

How to Make a Connection

Connection Procedure

1. Ground yourself and all devices. Wear a grounded wrist strap and work on
2. Visually inspect the connectors. Refer to
3. If necessary, clean the connectors. Refer to
4. Carefully align the connectors. The male connector center pin must slip
5. Push the connectors straight together. Do not twist or screw them
Do not twist one connector into the other (like inserting a light bulb). This
happens when you turn the device body, rather than the connector nut.
Major damage to the center conductor and the outer conductor can occur
if the device body is twisted.
6. Initial tightening can be done by hand, or with a 6 mm open-end wrench.
At this point, all you want is for the outer conductors to make gentle
contact on both mating surfaces. Use very light finger pressure (no more than 2
inch–pounds of torque).
7. Relieve any side pressure on the connection from long or heavy devices, or

together. As the center conductors mate, there is usually a slight
resistance.
Tighten until "snug" or where the connectors are first making contact. The
preliminary connection is tight enough when the mating plane surfaces
make uniform, light contact. Do not overtighten this connection.
