Connections
Good connections are essential for accurate measurements and require a skilled operator.
The most common cause of measurement error is poor connections.
How to Make a Connection
Preliminary Connection
1. Ground yourself and all devices. Wear a grounded wrist strap and work on an antistatic
mat.
2. Visually inspect the connectors. Refer to
3. If necessary, clean the connectors.
4. Use a connector gage to verify that all center conductors are within pin depth values in
Table 2-3 on page 2-4.
5. Carefully align the connectors. The male connector center pin must slip concentrically
into the contact finger of the female connector.
6. Push the connectors straight together. Do not twist or screw them together. As the
center conductors mate, there is usually a slight resistance.
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.
7. The preliminary connection is tight enough when the mating plane surfaces make
uniform, light contact. Do not overtighten this connection.
A connection in which the outer conductors make gentle contact at all points on both
mating surfaces is sufficient. Very light finger pressure is enough.
8. Make sure the connectors are properly supported. Relieve any side pressure on the
connection from long or heavy devices or cables.
