Use a lint-free swab or cleaning cloth moistened with isopropyl alcohol to remove any
dirt or stubborn contaminants on a connector that cannot be removed with compressed
air or nitrogen. Refer to
cleaning swabs.
a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab.
b. Clean the connector threads.
c. Let the alcohol evaporate, then blow the threads dry with a gentle stream of clean,
low-pressure compressed air or nitrogen. Always completely dry a connector before
you reassemble or use it.
3. Clean the Mating Plane Surfaces
a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab.
b. Clean the center and outer conductor mating plane surfaces. Refer to
page
2-3. When cleaning a female connector, avoid snagging the swab on the center
conductor contact fingers by using short strokes.
c. Let the alcohol evaporate, then blow the connector dry with a gentle stream of clean,
low-pressure compressed air or nitrogen. Always completely dry a connector before
you reassemble or use it.
4. Reinspect
Inspect the connector again to make sure that no particles or residue are present.
Connections
Good connections require a skilled operator. The most common cause of measurement error
is bad connections. The following procedures illustrate how to make good connections.
How to Make a Connection
Preliminary Connection
1. Ground yourself and all devices. Wear a grounded wrist strap and work on a grounded,
conductive table mat. Refer to
precautions.
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 concentrically
into the contact finger of the female connector.
5. Push the connectors straight together.
CAUTION
Do not turn the device body. Only turn the connector nut. Damage to the
center conductor can occur if the device body is twisted.
