Use, Maintenance, and Care of the Devices
Gaging Connectors

Gaging the Airline

The airlines in this kit are measured and matched for length at the factory using

special fixtures and gages. Because the gages supplied in the calibration kits

do not have the accuracy of the factory gages, use the following procedure for

very general results only. Perform this procedure whenever you suspect that a

center conductor has been switched with another airline or that a device has

been damaged.

Select a male connector gage and male short for this procedure. Refer to

Table 6-3 on page 5

for part numbers.

Inspect and clean the mating surfaces and connector threads of the short,

airline, and gage. Refer to

“Visual Inspection”

and

“Cleaning Connectors”

earlier in this chapter.

Zero the connector gage (refer to

Figure 3-3

While holding the gage by the barrel and without turning the gage

or the short, connect the gage to the short by interconnecting the

male and female connectors. Connect the nut finger tight. Do not

overtighten.

Using an open-end wrench to keep the device body from rotating,

use the torque wrench recommended for use with this kit to tighten

the connecting nut to the specified torque. Refer to

“Final

Connection Using a Torque Wrench” on page 17

for additional

information.

As you watch the gage pointer, gently tap the barrel of the gage to

settle the reading.

The gage pointer should line up exactly with the zero mark on the

gage. If not, loosen the dial lock screw on the gage and rotate the

gage dial so that the pointer is aligned with the zero mark. Tighten

the dial lock screw.

Without turning the short or the gage, remove the short from the

gage. Refer to

“How to Separate a Connection” on page 20

Always hold a connector gage by the gage barrel, below the dial indicator.

This gives the best stability, and improves measurement accuracy.
