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

Ground yourself and all devices. Wear a grounded wrist strap and work on

a grounded, conductive table mat. Refer to

“Electrostatic Discharge” on

page 1

for ESD precautions.

Visually inspect the connectors. Refer to

“Visual Inspection” on page 3

If necessary, clean the connectors. Refer to

“Cleaning Connectors” on

page 5

Use a connector gage to verify that all center conductors are within the

pin depth values listed in

Table 2-2 on page 4

. Refer to

“Gaging

Connectors” on page 7

Carefully align the connectors. The male connector center pin must slip

concentrically into the contact finger of the female connector.

Push the connectors straight together and tighten the connector nut

finger tight.

Do not twist or screw the connectors together. As the center conductors

mate, there is usually a slight resistance.

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.

Make sure the connectors are properly supported. Relieve any side

pressure on the connection from long or heavy devices or cables.

not

turn the device body. Turn only the connector nut. Damage to the

center conductor can occur if the device body is rotated.
