Use, Maintenance, and Care of the Devices

Connections

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

“Electrostatic Discharge” on page 3-2

for ESD

precautions.

2. Visually inspect the connectors. Refer to

“Visual Inspection” on page 3-3

3. If necessary, clean the connectors. Refer to

“Cleaning Connectors” on page 3-4

.

4. Use a connector gage to verify that all center conductors are within the observed pin

depth values in

Table 2-2 on page 2-4

. Refer to

“Gaging Connectors” on page 3-6

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 and tighten the connector nut finger tight.

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.

Do not twist or screw the connectors together. As the center conductors mate, there is
usually a slight resistance.

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 to accomplish this.

8. Make sure the connectors are properly supported. Relieve any side pressure on the

connection from long or heavy devices or cables.

Final Connection Using a Torque Wrench

Use a torque wrench to make a final connection.

torque wrench recommended for use with the calibration kit. A torque wrench is included
in the calibration kit. Refer to

Table 6-1 on page 6-2

for replacement part number and

ordering information.
